Chemical Structure

Sodium Methanesulfinate CAS 20277-69-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium Methanesulfinate.

CATO supplies Sodium Methanesulfinate (CAS 20277-69-4), a certified reference material (molecular formula CH3O2SNa, MW 102.08 g/mol) for analytical method development and quality control.

The molecular framework of Sodium Methanesulfinate (CH3O2SNa) 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.

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.
