Chemical Structure

Sodium 2,3-Dimercaptopropanesulfonate Monohydrate CAS 207233-91-8 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 2,3-Dimercaptopropanesulfonate Monohydrate.

Sodium 2,3-Dimercaptopropanesulfonate Monohydrate (CAS 207233-91-8), molecular formula C3H7O3S3NaH2O and molecular weight 228.27 g/mol, is a CATO reference standard with documented purity and traceability.

Sodium 2,3-Dimercaptopropanesulfonate Monohydrate (C3H7O3S3NaH2O) 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.

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.
