1,3-Diphenyl-4,5-dihydro-1H-pyrazole-5-carbonitrile (CAS 3426-35-5) is a high-purity analytical reference standard with the molecular formula C16H13N3 and a molecular weight of 247.29 g/mol.
1,3-Diphenyl-4,5-dihydro-1H-pyrazole-5-carbonitrile (C16H13N3) 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 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 1,3-Diphenyl-4,5-dihydro-1H-pyrazole-5-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.
