Chemical Structure

(E)-3-(5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-1-(3,4-dichlorophenyl)prop-2-en-1-one CAS 956376-47-9 chemical structure

Description

The occurrence of (E)-3-(5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-1-(3,4-dichlorophenyl)prop-2-en-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-3-(5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-1-(3,4-dichlorophenyl)prop-2-en-1-one (CAS 956376-47-9), a certified reference material (molecular formula C14H8Cl3F3N2O, MW 383.58 g/mol) for analytical method development and quality control.

The molecular framework of (E)-3-(5-chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-1-(3,4-dichlorophenyl)prop-2-en-1-one (C14H8Cl3F3N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
