Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 192.23 g/mol gives Benzo[b]thiophene-2-acetic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Benzo[b]thiophene-2-acetic Acid (CAS 75894-07-4), a certified reference material (molecular formula C10H8O2S, MW 192.23 g/mol) for analytical method development and quality control.
The molecular framework of Benzo[b]thiophene-2-acetic Acid (C10H8O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Benzo[b]thiophene-2-acetic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
