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