Chemical Structure
Description
The occurrence of 6-Amino-2-chloro-4-methyl-4,6,7,8-tetrahydro-5H-thieno[3,2-b]azepin-5-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Amino-2-chloro-4-methyl-4,6,7,8-tetrahydro-5H-thieno[3,2-b]azepin-5-one (CAS 2124261-91-0) is a high-purity analytical reference standard with the molecular formula C9H11ClN2OS and a molecular weight of 230.71 g/mol.
The molecular framework of 6-Amino-2-chloro-4-methyl-4,6,7,8-tetrahydro-5H-thieno[3,2-b]azepin-5-one (C9H11ClN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
