2-((tert-Butoxycarbonyl)amino)benzo[b]thiophene-3-carboxylic acid CAS 923009-99-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((tert-Butoxycarbonyl)amino)benzo[b]thiophene-3-carboxylic acid.

CATO supplies 2-((tert-Butoxycarbonyl)amino)benzo[b]thiophene-3-carboxylic acid (CAS 923009-99-8), a certified reference material (molecular formula C14H15NO4S, MW 293.34 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((tert-Butoxycarbonyl)amino)benzo[b]thiophene-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), 2-((tert-Butoxycarbonyl)amino)benzo[b]thiophene-3-carboxylic 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.
