Chemical Structure

1,1-Methanediyl Bismethanethiosulfonate CAS 22418-52-6 chemical structure

Description

The molecular framework of 1,1-Methanediyl Bismethanethiosulfonate (C3H8O4S4) is characterized by a sulfone group, a carboxylic acid group, an ether linkage. 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.

CATO supplies 1,1-Methanediyl Bismethanethiosulfonate (CAS 22418-52-6), a certified reference material (molecular formula C3H8O4S4, MW 236.35 g/mol) for analytical method development and quality control.

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.
