Sodium 2-sulfidopyridine 1-oxide hydrate CAS 304675-78-3

Description

The occurrence of Sodium 2-sulfidopyridine 1-oxide hydrate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Sodium 2-sulfidopyridine 1-oxide hydrate (CAS 304675-78-3), a certified reference material (molecular formula C5H4NOSNaH2O, MW 167.16 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Sodium 2-sulfidopyridine 1-oxide hydrate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
