Chemical Structure

1-Methyl-3-(3-methyl-1,1-dioxidotetrahydrothiophen-3-yl)thiourea CAS 507456-16-8 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.

1-Methyl-3-(3-methyl-1,1-dioxidotetrahydrothiophen-3-yl)thiourea (CAS 507456-16-8) is a high-purity analytical reference standard with the molecular formula C7H14N2O2S2 and a molecular weight of 222.33 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1-Methyl-3-(3-methyl-1,1-dioxidotetrahydrothiophen-3-yl)thiourea is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.33 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.

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.
