4-Methyl-N-(4-(phenylamino)phenyl)benzenesulfonamide CAS 100-93-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methyl-N-(4-(phenylamino)phenyl)benzenesulfonamide.

CATO supplies 4-Methyl-N-(4-(phenylamino)phenyl)benzenesulfonamide (CAS 100-93-6), a certified reference material (molecular formula C19H18N2O2S, MW 338.42 g/mol) for analytical method development and quality control.

4-Methyl-N-(4-(phenylamino)phenyl)benzenesulfonamide (C19H18N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
