Chemical Structure
Description
The occurrence of N-Benzyl-4-(diphenylphosphoryl)benzamide is closely related to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-Benzyl-4-(diphenylphosphoryl)benzamide (CAS 90304-92-0), a certified reference material (molecular formula C26H22NO2P, MW 411.43 g/mol) for analytical method development and quality control.
Structurally, N-Benzyl-4-(diphenylphosphoryl)benzamide (C26H22NO2P) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.5, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 411.43 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
