1-Benzyl-3-cyclopropyl-1H-pyrazole-5-carboxylic acid (CAS 1239785-16-0), molecular formula C14H14N2O2 and molecular weight 242.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H14N2O2, 1-Benzyl-3-cyclopropyl-1H-pyrazole-5-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
