Chemical Structure

2-Oxo-N,2-diphenylacetamide CAS 4732-66-5 chemical structure

Description

2-Oxo-N,2-diphenylacetamide (C14H11NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2-Oxo-N,2-diphenylacetamide (CAS 4732-66-5) is a high-purity analytical reference standard with the molecular formula C14H11NO2 and a molecular weight of 225.24 g/mol.

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 manufactures 2-Oxo-N,2-diphenylacetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
