Chemical Structure
Description
Structurally, 3-(4-Chlorophenyl)-1-(p-tolyl)-1H-pyrazole-4-carbaldehyde (C17H13ClN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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 296.75 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 3-(4-Chlorophenyl)-1-(p-tolyl)-1H-pyrazole-4-carbaldehyde (CAS 36640-46-7), a certified reference material (molecular formula C17H13ClN2O, MW 296.75 g/mol) for analytical method development and quality control.
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.
