Chemical Structure

2-Methyl-6-phenylthieno[2,3-d]pyrimidine-4-thiol CAS 315696-68-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyl-6-phenylthieno[2,3-d]pyrimidine-4-thiol.

CATO supplies 2-Methyl-6-phenylthieno[2,3-d]pyrimidine-4-thiol (CAS 315696-68-5), a certified reference material (molecular formula C13H10N2S2, MW 258.36 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-Methyl-6-phenylthieno[2,3-d]pyrimidine-4-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.36 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.

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.
