Chemical Structure

Trimethylsulfoxonium Bromide CAS 25596-24-1 chemical structure

Description

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.

Trimethylsulfoxonium Bromide (CAS 25596-24-1) is a high-purity analytical reference standard with the molecular formula C3H9OSBr and a molecular weight of 173.07 g/mol.

Trimethylsulfoxonium Bromide (C3H9OSBr) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
