Chemical Structure

3-(3-Chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde CAS 36640-43-4 chemical structure

Description

3-(3-Chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (C16H11ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 3-(3-Chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 36640-43-4), a certified reference material (molecular formula C16H11ClN2O, MW 282.72 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.
