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 7-chloro-[1,2,4]triazolo[1,5-c]pyrimidine-2-carboxylate.
ethyl 7-chloro-[1,2,4]triazolo[1,5-c]pyrimidine-2-carboxylate (CAS 1375474-57-9), molecular formula C8H15ClN4O2 and molecular weight 234.68 g/mol, is a CATO reference standard with documented purity and traceability.
ethyl 7-chloro-[1,2,4]triazolo[1,5-c]pyrimidine-2-carboxylate (C8H15ClN4O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 7-chloro-[1,2,4]triazolo[1,5-c]pyrimidine-2-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.
