Chemical Structure
Description
CATO manufactures 2-(ethenesulfonyl)acetic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2-(ethenesulfonyl)acetic acid (CAS 20854-29-9), molecular formula C4H6O4S and molecular weight 150.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(ethenesulfonyl)acetic acid (C4H6O4S) is characterized by a carbohydrate-derived structure, a sulfone group. 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.
