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 Ethyl 2-(chloromethyl)-5-methyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidine-6-carboxylate.
Ethyl 2-(chloromethyl)-5-methyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidine-6-carboxylate (CAS 89567-06-6), molecular formula C11H11ClN2O3S and molecular weight 286.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-(chloromethyl)-5-methyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidine-6-carboxylate (C11H11ClN2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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.
CATO manufactures Ethyl 2-(chloromethyl)-5-methyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidine-6-carboxylate 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.
