Chemical Structure

5-Methylthiazolidine-2-thione CAS 1437-90-7 chemical structure

Description

Owing to a nitrile group, sulfur-containing functionality, 5-Methylthiazolidine-2-thione is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 5-Methylthiazolidine-2-thione (CAS 1437-90-7), a certified reference material (molecular formula C4H7NS2, MW 133.24 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.
