Chemical Structure
Description
CATO supplies 1-(2-Fluorophenyl)-3-(p-tolyl)-1H-pyrazole-4-carbaldehyde (CAS 618098-69-4), a certified reference material (molecular formula C17H13FN2O, MW 280.30 g/mol) for analytical method development and quality control.
Structurally, 1-(2-Fluorophenyl)-3-(p-tolyl)-1H-pyrazole-4-carbaldehyde (C17H13FN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 280.30 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
