Chemical Structure

N-(2,2-Dichloro-1-(diphenylphosphoryl)vinyl)benzamide CAS 55785-68-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,2-Dichloro-1-(diphenylphosphoryl)vinyl)benzamide.

N-(2,2-Dichloro-1-(diphenylphosphoryl)vinyl)benzamide (CAS 55785-68-7), molecular formula C21H16Cl2NO2P and molecular weight 416.24 g/mol, is a CATO reference standard with documented purity and traceability.

N-(2,2-Dichloro-1-(diphenylphosphoryl)vinyl)benzamide (C21H16Cl2NO2P) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
