Chemical Structure
Description
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.
CATO supplies 51608-60-7 Benzenesulfonamide, 4-methyl-N-(phenylmethylene)-, (E)- CTK1G4448 (CAS 51608-60-7), a certified reference material (molecular formula C14H25NO2S, MW 271.42 g/mol) for analytical method development and quality control.
51608-60-7 Benzenesulfonamide, 4-methyl-N-(phenylmethylene)-, (E)- CTK1G4448 (C14H25NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
