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 1-Benzyl-3-(2,5-dimethylphenyl)thiourea (CAS 131389-22-5), a certified reference material (molecular formula C16H18N2S, MW 270.39 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1-Benzyl-3-(2,5-dimethylphenyl)thiourea is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 270.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
