Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(1,3-Diphenyl-1H-pyrazol-5-yl)aniline (CAS 320576-22-5), molecular formula C21H17N3 and molecular weight 311.38 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1,3-Diphenyl-1H-pyrazol-5-yl)aniline (C21H17N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-(1,3-Diphenyl-1H-pyrazol-5-yl)aniline 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.
