3-(2-Chlorophenyl)-5-[(E)-2-[(3-chlorophenyl)amino]ethenyl]-1,2-oxazole-4-carbonitrile CAS 320415-79-0

Description

Compared with other compounds in its class, the molecular weight of 356.21 g/mol gives 3-(2-Chlorophenyl)-5-[(E)-2-[(3-chlorophenyl)amino]ethenyl]-1,2-oxazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-(2-Chlorophenyl)-5-[(E)-2-[(3-chlorophenyl)amino]ethenyl]-1,2-oxazole-4-carbonitrile (CAS 320415-79-0), a certified reference material (molecular formula C18H11Cl2N3O, MW 356.21 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(2-Chlorophenyl)-5-[(E)-2-[(3-chlorophenyl)amino]ethenyl]-1,2-oxazole-4-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
