Description
CATO manufactures 4-(3-Phenyl-4,5-dihydro-1H-pyrazol-1-yl)benzoic acid 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.
4-(3-Phenyl-4,5-dihydro-1H-pyrazol-1-yl)benzoic acid (CAS 26192-74-5) is a high-purity analytical reference standard with the molecular formula C16H14N2O2 and a molecular weight of 266.29 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-(3-Phenyl-4,5-dihydro-1H-pyrazol-1-yl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
