Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.66 g/mol gives 5-Chloro-3-(4-fluorophenyl)pyrazolo[1,5-a]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloro-3-(4-fluorophenyl)pyrazolo[1,5-a]pyrimidine (CAS 1956330-85-0) is a high-purity analytical reference standard with the molecular formula C12H7ClFN3 and a molecular weight of 247.66 g/mol.
The molecular framework of 5-Chloro-3-(4-fluorophenyl)pyrazolo[1,5-a]pyrimidine (C12H7ClFN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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.
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 5-Chloro-3-(4-fluorophenyl)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.
