Chemical Structure
Description
CATO supplies 4-Chloro-6-isopropylthieno[2,3-d]pyrimidine (CAS 439692-52-1), a certified reference material (molecular formula C9H9ClN2S, MW 212.70 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-6-isopropylthieno[2,3-d]pyrimidine (C9H9ClN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-6-isopropylthieno[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.
