Chemical Structure
Description
CATO supplies Methanesulfinic acid (CAS 17696-73-0), a certified reference material (molecular formula CH4O2S, MW 80.11 g/mol) for analytical method development and quality control.
The molecular framework of Methanesulfinic acid (CH4O2S) is characterized by 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methanesulfinic 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.
