Methyl Methanethiosulfonate-d3 CAS 55800-37-8 chemical structure

Description

CATO supplies Methyl Methanethiosulfonate-d3 (CAS 55800-37-8), a certified reference material (molecular formula C2H6O2S2, MW 126.20 g/mol) for analytical method development and quality control.

Methyl Methanethiosulfonate-d3 (C2H6O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
