4-Chloro-2-(pyridin-4-yl)-5-(p-tolyl)thieno[2,3-d]pyrimidine CAS 885460-94-6 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 4-Chloro-2-(pyridin-4-yl)-5-(p-tolyl)thieno[2,3-d]pyrimidine.

4-Chloro-2-(pyridin-4-yl)-5-(p-tolyl)thieno[2,3-d]pyrimidine (CAS 885460-94-6) is a high-purity analytical reference standard with the molecular formula C18H12ClN3S and a molecular weight of 337.83 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-Chloro-2-(pyridin-4-yl)-5-(p-tolyl)thieno[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.83 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.

As a certified reference material (CRM), 4-Chloro-2-(pyridin-4-yl)-5-(p-tolyl)thieno[2,3-d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
