Chemical Structure

3-(4-Chlorophenyl)-1-(4-(methylsulfonyl)phenyl)-4,5-dihydro-1H-pyrazole CAS 14295-72-8 chemical structure

Description

3-(4-Chlorophenyl)-1-(4-(methylsulfonyl)phenyl)-4,5-dihydro-1H-pyrazole (C16H15ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-(4-(methylsulfonyl)phenyl)-4,5-dihydro-1H-pyrazole (CAS 14295-72-8), a certified reference material (molecular formula C16H15ClN2O2S, MW 334.82 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.
