Chemical Structure

3-Sulfopropanoic acid CAS 44826-45-1 chemical structure

Description

The occurrence of 3-Sulfopropanoic acid is closely related to a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Sulfopropanoic acid (CAS 44826-45-1), a certified reference material (molecular formula C3H6O5S, MW 154.14 g/mol) for analytical method development and quality control.

Structurally, 3-Sulfopropanoic acid (C3H6O5S) contains a sulfone group, a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 154.14 g/mol, it falls into the medium-molecular-weight range.

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.
