6-sulfanylpyridine-2-carboxylic acid CAS 14716-87-1

Description

Compared with other compounds in its class, the molecular weight of 161.22 g/mol gives 6-sulfanylpyridine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-sulfanylpyridine-2-carboxylic acid (CAS 14716-87-1) is a high-purity analytical reference standard with the molecular formula C6H11NO2S and a molecular weight of 161.22 g/mol.

6-sulfanylpyridine-2-carboxylic acid (C6H11NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
