1-(4-Fluorophenyl)-3-(3-methylphenyl)-1h-pyrazole-4-carbaldehyde CAS 956571-56-5

Description

The occurrence of 1-(4-Fluorophenyl)-3-(3-methylphenyl)-1h-pyrazole-4-carbaldehyde is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(4-Fluorophenyl)-3-(3-methylphenyl)-1h-pyrazole-4-carbaldehyde (CAS 956571-56-5), a certified reference material (molecular formula C17H13FN2O, MW 280.30 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(4-Fluorophenyl)-3-(3-methylphenyl)-1h-pyrazole-4-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
