3-Hydroxypropanesulfonic acid CAS 15909-83-8 chemical structure

Description

As a certified reference material (CRM), 3-Hydroxypropanesulfonic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

3-Hydroxypropanesulfonic acid (CAS 15909-83-8) is a high-purity analytical reference standard with the molecular formula C3H8O4S and a molecular weight of 140.16 g/mol.

3-Hydroxypropanesulfonic acid (C3H8O4S) contains a sulfone group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
