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 5-(2-Chlorophenyl)-N-(4-chlorophenyl)furan-2-carboxamide.
CATO supplies 5-(2-Chlorophenyl)-N-(4-chlorophenyl)furan-2-carboxamide (CAS 199458-91-8), a certified reference material (molecular formula C17H11Cl2NO2, MW 332.18 g/mol) for analytical method development and quality control.
5-(2-Chlorophenyl)-N-(4-chlorophenyl)furan-2-carboxamide (C17H11Cl2NO2) 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.
