Description

The molecular framework of 956-04-7 Chalcone, 4-chloro- (6CI,7CI,8CI) 4-Chlorochalcone 2-Propen-1-one, 3-(4-chlorophenyl)-1-phenyl- 2-07-00-00427 (Beilstein Handbook Reference) AI3-19969 BRN 1105953 (4-Chlorobenzylidene)acetophenone p-Chlorochalcone 3-(4-Chlorophenyl)-1-phenyl-2-propen-1-one p-Chlorostyryl phenyl ketone 4-Chlorostyryl phenyl ketone EINECS 213-476-1 NSC 636920 (C15H23ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies 956-04-7 Chalcone, 4-chloro- (6CI,7CI,8CI) 4-Chlorochalcone 2-Propen-1-one, 3-(4-chlorophenyl)-1-phenyl- 2-07-00-00427 (Beilstein Handbook Reference) AI3-19969 BRN 1105953 (4-Chlorobenzylidene)acetophenone p-Chlorochalcone 3-(4-Chlorophenyl)-1-phenyl-2-propen-1-one p-Chlorostyryl phenyl ketone 4-Chlorostyryl phenyl ketone EINECS 213-476-1 NSC 636920 (CAS 956-04-7), a certified reference material (molecular formula C15H23ClO, MW 254.80 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
