Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-(5-oxo-3-propyl-4,5-dihydro-1h-pyraZol-1-yl)benzoic acid (CAS 701221-57-0), a certified reference material (molecular formula C13H14N2O3, MW 246.26 g/mol) for analytical method development and quality control.
Structurally, 3-(5-oxo-3-propyl-4,5-dihydro-1h-pyraZol-1-yl)benzoic acid (C13H14N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 246.26 g/mol, it falls into the medium-molecular-weight range. 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).
