5-(Sulfanylmethyl)thiophene-2-carboxylic acid CAS 14325-49-6

Description

Compared with other compounds in its class, the molecular weight of 174.24 g/mol gives 5-(Sulfanylmethyl)thiophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-(Sulfanylmethyl)thiophene-2-carboxylic acid (CAS 14325-49-6), a certified reference material (molecular formula C6H6O2S2, MW 174.24 g/mol) for analytical method development and quality control.

5-(Sulfanylmethyl)thiophene-2-carboxylic acid (C6H6O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
