Description
CATO supplies 3-Chloro-6-(4-chlorophenyl)-2-methylpyrazolo[1,5-a]pyrimidine (CAS 439107-64-9), a certified reference material (molecular formula C13H9Cl2N3, MW 278.14 g/mol) for analytical method development and quality control.
3-Chloro-6-(4-chlorophenyl)-2-methylpyrazolo[1,5-a]pyrimidine (C13H9Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-6-(4-chlorophenyl)-2-methylpyrazolo[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.
