Chemical Structure

1,4-Butanediyl Bismethanethiosulfonate CAS 55-99-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 278.43 g/mol gives 1,4-Butanediyl Bismethanethiosulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,4-Butanediyl Bismethanethiosulfonate (CAS 55-99-2), molecular formula C6H14O4S4 and molecular weight 278.43 g/mol, is a CATO reference standard with documented purity and traceability.

1,4-Butanediyl Bismethanethiosulfonate (C6H14O4S4) contains a sulfone group, a carboxylic acid group, a hydroxyl 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.
