Chemical Structure

2-sulfopropanoic acid CAS 55306-57-5 chemical structure

Description

2-sulfopropanoic acid (CAS 55306-57-5), molecular formula C3H6O5S and molecular weight 154.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-sulfopropanoic acid (C3H6O5S) is characterized by a sulfone group, a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

As a certified reference material (CRM), 2-sulfopropanoic 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.
