Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 226.68 g/mol gives 6-Chloro-3-hydroxy-4-methylbenzo[b]thiophene-2-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Chloro-3-hydroxy-4-methylbenzo[b]thiophene-2-carbaldehyde (CAS 856793-88-9), a certified reference material (molecular formula C10H7ClO2S, MW 226.68 g/mol) for analytical method development and quality control.
The molecular framework of 6-Chloro-3-hydroxy-4-methylbenzo[b]thiophene-2-carbaldehyde (C10H7ClO2S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 6-Chloro-3-hydroxy-4-methylbenzo[b]thiophene-2-carbaldehyde 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.
