CATO supplies 7-Chloro-2,5-dimethyl-3-(p-tolyl)pyrazolo[1,5-a]pyrimidine (CAS 1281233-89-3), a certified reference material (molecular formula C15H14ClN3, MW 271.74 g/mol) for analytical method development and quality control.
The molecular framework of 7-Chloro-2,5-dimethyl-3-(p-tolyl)pyrazolo[1,5-a]pyrimidine (C15H14ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 7-Chloro-2,5-dimethyl-3-(p-tolyl)pyrazolo[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.
