2-Hydroxy-2-(3-methylthiophen-2-yl)acetic acid CAS 1248481-32-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-2-(3-methylthiophen-2-yl)acetic acid.

2-Hydroxy-2-(3-methylthiophen-2-yl)acetic acid (CAS 1248481-32-4) is a high-purity analytical reference standard with the molecular formula C7H8O3S and a molecular weight of 172.20 g/mol.

2-Hydroxy-2-(3-methylthiophen-2-yl)acetic acid (C7H8O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 2-Hydroxy-2-(3-methylthiophen-2-yl)acetic acid 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.
