Chemical Structure

1,5-Diphenylpyrimidine-4(1H)-thione CAS 98381-58-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,5-Diphenylpyrimidine-4(1H)-thione (CAS 98381-58-9) is a high-purity analytical reference standard with the molecular formula C16H12N2S and a molecular weight of 264.34 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1,5-Diphenylpyrimidine-4(1H)-thione is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 264.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
