Description
CATO manufactures 4-(Dimethylamino)benzo[b]thiophene-2-carboxylic acid hydrochloride 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.
4-(Dimethylamino)benzo[b]thiophene-2-carboxylic acid hydrochloride (CAS 2137696-74-1) is a high-purity analytical reference standard with the molecular formula C11H11NO2SHCl and a molecular weight of 257.73 g/mol.
The molecular framework of 4-(Dimethylamino)benzo[b]thiophene-2-carboxylic acid hydrochloride (C11H11NO2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
