Chemical Structure

2-(4-Benzoylphenyl)-2-(2,4-dichlorophenyl)acetamide CAS 338965-57-4 chemical structure

Description

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.

CATO supplies 2-(4-Benzoylphenyl)-2-(2,4-dichlorophenyl)acetamide (CAS 338965-57-4), a certified reference material (molecular formula C21H15Cl2NO2, MW 384.26 g/mol) for analytical method development and quality control.

2-(4-Benzoylphenyl)-2-(2,4-dichlorophenyl)acetamide (C21H15Cl2NO2) contains a steroid core, 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, 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.

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.
