Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-7-(chlorodifluoromethyl)-2-methyl-5-(4-(trifluoromethyl)phenyl)pyrazolo[1,5-a]pyrimidine.
3-Chloro-7-(chlorodifluoromethyl)-2-methyl-5-(4-(trifluoromethyl)phenyl)pyrazolo[1,5-a]pyrimidine (CAS 439097-18-4) is a high-purity analytical reference standard with the molecular formula C15H8Cl2F5N3 and a molecular weight of 396.14 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 3-Chloro-7-(chlorodifluoromethyl)-2-methyl-5-(4-(trifluoromethyl)phenyl)pyrazolo[1,5-a]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Chloro-7-(chlorodifluoromethyl)-2-methyl-5-(4-(trifluoromethyl)phenyl)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.
