Chemical Structure

(Z)-2,2,2-trifluoro-1-(1-(4-fluorophenyl)-2-methyl-5-(4-(methylsulfonyl)phenyl)-1H-pyrrol-3-yl)ethan-1-one O-(4-chlorobenzoyl) oxime CAS 860788-01-8 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 (Z)-2,2,2-trifluoro-1-(1-(4-fluorophenyl)-2-methyl-5-(4-(methylsulfonyl)phenyl)-1H-pyrrol-3-yl)ethan-1-one O-(4-chlorobenzoyl) oxime (CAS 860788-01-8), a certified reference material (molecular formula C27H19ClF4N2O4S, MW 578.96 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (Z)-2,2,2-trifluoro-1-(1-(4-fluorophenyl)-2-methyl-5-(4-(methylsulfonyl)phenyl)-1H-pyrrol-3-yl)ethan-1-one O-(4-chlorobenzoyl) oxime is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 578.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
