Chemical Structure

N-Butanesulfinic acid sodium salt CAS 16642-95-8 chemical structure

Description

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.

CATO supplies N-Butanesulfinic acid sodium salt (CAS 16642-95-8), a certified reference material (molecular formula C4H9O2SNa, MW 144.16 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, N-Butanesulfinic acid sodium salt is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
