摘要
Three new impurities of d-Biotin were synthesized:(2S,3S,4S)-5-(3,4-diamino-tetrahydro-thiophen-2-yl)-pentanoic acid,(3aS,4S,6aR)-hexahydro-1-thia-3,4a-diaza-cyclopenta inden-4-one and(3aS,4S,6aR)-4-(5’-Oxo-hexyl)-tetrahydro-thieno-imidazol-2-one.Structures of target compounds were confirmed by NMR and so on.Our work further improved the research on the impurities of d-biotin,and can be applied to the quality control and quality assurance of d-biotin.
Three new impurities of d-Biotin were synthesized: ( 2S, 3 S, 4S ) -5- ( 3,4 -diamino- tetrahydro -thiophen-2 -yl ) -pentanoie acid, (3aS,4S, 6aR) -hexahydro-1 -thia-3,4a-diaza-cyclopenta [ cd ] i nden-4-one and (3 aS,4S,6aR) -4- (5' -Oxo-hexyl ) -tetrahydro-thieno-[3,6] imidazol-2-one. Structures of target compounds were confirmed by NMR and so on. Our work further improved the research on the impurities of d-biotin, and can be applied to the quality control and quality assurance of d-biotin.
