Inhalation studies ... in which rats and mice were exposed to lethal concn (27.8-29%) revealed that n-butane is absorbed and distributed to various tissues. After 4 hr of respiratory exposure, surviving rats were sacrificed ... concn of butane were ... highest in perinephric fat (2086 ppm), then brain (750 ppm), spleen (522 ppm), liver (492 ppm), and kidney (441 ppm). In mice exposed to 2 hr of butane vapors, the brain levels of n-butane were found to be 779 ppm. In both rats and mice the brain levels of n-butane correlated with the degree of CNS depression ... Dermal absorption of n-butane vapors has not been reported. However, dermal penetration of butane would not be expected to occur to any large extent since skin contact is transient because of volatility.

Because of its volatile nature, elimination of butane by exhalation can be anticipated.

A study was conducted to establish whether volatile hydrocarbons, such as propane, n-butane and iso-butane, are metabolized in mice or not. In mice having inhaled these gases, isopropanol and acetone were yielded from propane, sec-butanol and methyl ethyl ketone from n-butane, and tert-butanol from iso-butane as the respective metabolites. In addition, liver microsomes were found to contain the enzymic system participating in these metabolisms. In vitro reactions with liver microsomes produced isopropanol from propane, sec-butanol from n-butane, and tert-butanol from iso-butane. It was assumed that hydrocarbons were first converted to (omega-1)-alcohols by microsomal enzyme system and then to corresponding ketones by alcohol dehydrogenase.

Microsomal enzyme systems have been found that oxidize butane to its parent alcohol.

Hydroxylation of butane ... /occurs/ in rat liver microsomes to yield 2-butanol as the major metabolite. n-Butane is the lowest molecular weight alkane ... demonstrated to substrate-bind with cytochrome p450. ... If 2-butanol is the major metabolite formed in mammals, it would be expected to be eliminated in expired air. ... 2-Butanol may also be conjugated with glucuronic acid or be oxidized to methyl ethyl ketone which in turn is expired.

Purified liquefied petroleum gas (LPG), a mixture of butane, isobutane, and propane, is commonly abused by inhalation. Little is known about the mammalian metabolism of these substances. Metabolism of other hydrocarbons, including n-hexane and cyclohexane, has been studied in vitro using a range of liver preparations, with metabolites analyzed by static headspace techniques... Cyclohexanol and cyclohexanone were formed from cyclohexane and 1-, 2-, and 3-hexanol and 2-hexanone from n-hexane as predicted. Secondary alcohols are found for the other compounds studied, except for propene and isobutane, together with 2-propanone and 2-butanone from propane and n-butane, respectively. Samples from three individuals who died following LPG abuse contained a range of putative n-butane metabolites: n-butanol, 2-butanol, 2,3-butanediol, 3-hydroxy-2-butanone, and 2,3-butanedione. To /the authors/ knowledge, the last three compounds have not been proposed as metabolites of n-butane in man. These might be produced through similar metabolic pathways to those of n-hexane and n-heptane...

Based on kinetic studies ... with ethane and n-pentane, the elimination half-life of n-butane can be expected to be closer to that of n-pentane (half life= 0.13 hr, at nonsaturating concn).
Snyder, R. (ed.) Ethel Browning's Toxicity and Metabolism of Industrial Solvents. 2nd ed. Volume 1: Hydrocarbons. Amsterdam - New York - Oxford: Elsevier, 1987., p. 269
Its elimination half-life is 0.13 hr at nonsaturating concns.

...Not infrequently intentional butane inhalation results in high morbidity and mortality. A fatal outcome of butane abuse can be caused by asphyxia, cardiac arrhythmia or trauma. The reported number of cases in which death was the consequence of pure butane inhalation is limited, and in most cases a mixture of propellants was involved. This report covers two cases of sudden death due to the sniffing of a cigarette lighter refill containing butane. Autopsy was followed by toxicological, pathohistological and immunohistochemical analysis. Butane gas was confirmed in samples of blood, urine, brain and lungs... Histology showed almost identical changes in the lungs and heart in both cases. The morphology of heart damage on standard H/E stains was of special interest because it displayed all the characteristics of chronic and acute myocardial hypoxia found in the absence of atherosclerotic heart disease. In order to confirm early cardiac death caused by asphyxia due to butane inhalation a panel of immunohistochemical agents was used...

PharmaCompass offers a list of Butane API manufacturers, exporters & distributors, which can be sorted by GMP, USDMF, JDMF, KDMF, CEP (COS), WC, Price,and more, enabling you to easily find the right Butane manufacturer or Butane supplier for your needs.
Send us enquiries for free, and we will assist you in establishing a direct connection with your preferred Butane manufacturer or Butane supplier.
PharmaCompass also assists you with knowing the Butane API Price utilized in the formulation of products. Butane API Price is not always fixed or binding as the Butane Price is obtained through a variety of data sources. The Butane Price can also vary due to multiple factors, including market conditions, regulatory modifications, or negotiated pricing deals.
A Butane manufacturer is defined as any person or entity involved in the manufacture, preparation, processing, compounding or propagation of Butane, including repackagers and relabelers. The FDA regulates Butane manufacturers to ensure that their products comply with relevant laws and regulations and are safe and effective to use. Butane API Manufacturers are required to adhere to Good Manufacturing Practices (GMP) to ensure that their products are consistently manufactured to meet established quality criteria.
A Butane supplier is an individual or a company that provides Butane active pharmaceutical ingredient (API) or Butane finished formulations upon request. The Butane suppliers may include Butane API manufacturers, exporters, distributors and traders.
click here to find a list of Butane suppliers with USDMF, JDMF, KDMF, CEP, GMP, COA and API Price related information on PharmaCompass.
A Butane DMF (Drug Master File) is a document detailing the whole manufacturing process of Butane active pharmaceutical ingredient (API) in detail. Different forms of Butane DMFs exist exist since differing nations have different regulations, such as Butane USDMF, ASMF (EDMF), JDMF, CDMF, etc.
A Butane DMF submitted to regulatory agencies in the US is known as a USDMF. Butane USDMF includes data on Butane's chemical properties, information on the facilities and procedures used, and details about packaging and storage. The Butane USDMF is kept confidential to protect the manufacturer’s intellectual property.

Butane Active pharmaceutical ingredient (API) is produced in GMP-certified manufacturing facility.
GMP stands for Good Manufacturing Practices, which is a system used in the pharmaceutical industry to make sure that goods are regularly produced and monitored in accordance with quality standards. The FDA’s current Good Manufacturing Practices requirements are referred to as cGMP or current GMP which indicates that the company follows the most recent GMP specifications. The World Health Organization (WHO) has its own set of GMP guidelines, called the WHO GMP. Different countries can also set their own guidelines for GMP like China (Chinese GMP) or the EU (EU GMP).
PharmaCompass offers a list of Butane GMP manufacturers, exporters & distributors, which can be sorted by USDMF, JDMF, KDMF, CEP (COS), WC, API price, and more, enabling you to easily find the right Butane GMP manufacturer or Butane GMP API supplier for your needs.
A Butane CoA (Certificate of Analysis) is a formal document that attests to Butane's compliance with Butane specifications and serves as a tool for batch-level quality control.
Butane CoA mostly includes findings from lab analyses of a specific batch. For each Butane CoA document that a company creates, the USFDA specifies specific requirements, such as supplier information, material identification, transportation data, evidence of conformity and signature data.
Butane may be tested according to a variety of international standards, such as European Pharmacopoeia (Butane EP), Butane JP (Japanese Pharmacopeia) and the US Pharmacopoeia (Butane USP).
