Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(4-Fluorophenyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile.
7-(4-Fluorophenyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 320417-15-0), molecular formula C13H7FN4 and molecular weight 238.22 g/mol, is a CATO reference standard with documented purity and traceability.
7-(4-Fluorophenyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (C13H7FN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
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 7-(4-Fluorophenyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile 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.
