Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, 1,1-Dimethyl-3-(meta-tolyl)-2-thiourea is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.34 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.
1,1-Dimethyl-3-(meta-tolyl)-2-thiourea (CAS 21540-35-2), molecular formula C10H20N2S and molecular weight 200.34 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
