3-Sulfinothiophene-2-carboxylic acid CAS 123016-79-5

Description

Compared with other compounds in its class, the molecular weight of 192.21 g/mol gives 3-Sulfinothiophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Sulfinothiophene-2-carboxylic acid (CAS 123016-79-5), a certified reference material (molecular formula C5H4O4S2, MW 192.21 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, a sulfone group, 3-Sulfinothiophene-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.21 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.

CATO manufactures 3-Sulfinothiophene-2-carboxylic 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.
