Chemical Structure
Description
3-Chloro-6-methoxy-1-benzothiophene-2-carbonyl chloride (CAS 75998-29-7), molecular formula C10H6Cl2O2S and molecular weight 261.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-6-methoxy-1-benzothiophene-2-carbonyl chloride (C10H6Cl2O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 3-Chloro-6-methoxy-1-benzothiophene-2-carbonyl chloride 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.
