The occurrence of 2-Chloro-6-iodo-7,8-dihydro-4H-thieno[3,2-b]azepin-5(6H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-6-iodo-7,8-dihydro-4H-thieno[3,2-b]azepin-5(6H)-one (CAS 2124270-41-1) is a high-purity analytical reference standard with the molecular formula C8H7ClINOS and a molecular weight of 327.57 g/mol.
The molecular framework of 2-Chloro-6-iodo-7,8-dihydro-4H-thieno[3,2-b]azepin-5(6H)-one (C8H7ClINOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/iodine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-Chloro-6-iodo-7,8-dihydro-4H-thieno[3,2-b]azepin-5(6H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
