Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(4-(Benzyloxy)phenyl)-N'-(2-chloro-6-fluorobenzylidene)-1H-pyrazole-3-carbohydrazide (CAS 302918-10-1), molecular formula C24H18ClFN4O2 and molecular weight 448.88 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 5-(4-(Benzyloxy)phenyl)-N'-(2-chloro-6-fluorobenzylidene)-1H-pyrazole-3-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 448.88 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).
CATO manufactures 5-(4-(Benzyloxy)phenyl)-N'-(2-chloro-6-fluorobenzylidene)-1H-pyrazole-3-carbohydrazide 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.
