A .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEP of the European Pharmacopoeia monograph is often referred to as a .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane Certificate of Suitability (COS). The purpose of a .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEP is to show that the European Pharmacopoeia monograph adequately controls the purity of .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane EP produced by a given manufacturer. Suppliers of raw materials can prove the suitability of .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane to their clients by showing that a .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEP has been issued for it. The manufacturer submits a .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEP (COS) as part of the market authorization procedure, and it takes on the role of a .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEP holder for the record. Additionally, the data presented in the .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEP (COS) is managed confidentially and offers a centralized system acknowledged by numerous nations, exactly like the .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane DMF.
A .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEP (COS) is recognised by all 36 nations that make up the European Pharmacopoeia Convention. .alpha.-1,2,3,4,5,6-Hexachlorcyclohexane CEPs may be accepted in nations that are not members of the Ph. Eur. at the discretion of the authorities there.
