Chemical Structure
Description
CATO supplies 2,4-Dichloro-7-(difluoromethyl)thieno[3,2-d]pyrimidine (CAS 2816965-94-1), a certified reference material (molecular formula C7H2Cl2F2N2S, MW 255.07 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-Dichloro-7-(difluoromethyl)thieno[3,2-d]pyrimidine (C7H2Cl2F2N2S) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. 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.
CATO manufactures 2,4-Dichloro-7-(difluoromethyl)thieno[3,2-d]pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
