Chemical Structure

Trimethylsulfonium Iodide CAS 2181-42-2 chemical structure

Description

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.

CATO supplies Trimethylsulfonium Iodide (CAS 2181-42-2), a certified reference material (molecular formula IC3H9S, MW 204.06 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, iodine substitution, Trimethylsulfonium Iodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
