Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-Chloro-2,5-dimethyl-3-phenylpyrazolo[1,5-a]pyrimidine (CAS 1144449-18-2), molecular formula C14H12ClN3 and molecular weight 257.72 g/mol, is a CATO reference standard with documented purity and traceability.
7-Chloro-2,5-dimethyl-3-phenylpyrazolo[1,5-a]pyrimidine (C14H12ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 7-Chloro-2,5-dimethyl-3-phenylpyrazolo[1,5-a]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.
