Chemical Structure
Description
2-Chloro-n-[3-(4-ethoxybenzoyl)-6-methyl-4,5,6,7-tetrahydro-1-benzothiophen-2-yl]acetamide (CAS 792954-21-3), molecular formula C20H22ClNO3S and molecular weight 391.91 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-n-[3-(4-ethoxybenzoyl)-6-methyl-4,5,6,7-tetrahydro-1-benzothiophen-2-yl]acetamide (C20H22ClNO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Chloro-n-[3-(4-ethoxybenzoyl)-6-methyl-4,5,6,7-tetrahydro-1-benzothiophen-2-yl]acetamide 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.
