Chemical Structure
Description
7-Chloro-3-(2-fluorophenyl)-2,5-dimethylpyrazolo[1,5-a]pyrimidine (C14H11ClFN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
7-Chloro-3-(2-fluorophenyl)-2,5-dimethylpyrazolo[1,5-a]pyrimidine (CAS 1204298-01-0), molecular formula C14H11ClFN3 and molecular weight 275.71 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
