N-(4-Chlorophenyl)-2,2-diphenylacetamide CAS 24765-98-8

Description

Compared with other compounds in its class, the molecular weight of 321.80 g/mol gives N-(4-Chlorophenyl)-2,2-diphenylacetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(4-Chlorophenyl)-2,2-diphenylacetamide (CAS 24765-98-8) is a high-purity analytical reference standard with the molecular formula C20H16ClNO and a molecular weight of 321.80 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-(4-Chlorophenyl)-2,2-diphenylacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.80 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.

As a certified reference material (CRM), N-(4-Chlorophenyl)-2,2-diphenylacetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
