Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 317.77 g/mol gives Ethyl 2-(2-chloro-2-phenylacetamido)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 2-(2-chloro-2-phenylacetamido)benzoate (CAS 864932-81-0), a certified reference material (molecular formula C17H16ClNO3, MW 317.77 g/mol) for analytical method development and quality control.
Ethyl 2-(2-chloro-2-phenylacetamido)benzoate (C17H16ClNO3) contains a steroid core, an amide group, 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.
