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 (3Z)-3-[(4-Methylphenyl)imino]-1-phenyl-2,3-dihydro-1H-indol-2-one (CAS 303984-52-3), a certified reference material (molecular formula C21H16N2O, MW 312.36 g/mol) for analytical method development and quality control.
(3Z)-3-[(4-Methylphenyl)imino]-1-phenyl-2,3-dihydro-1H-indol-2-one (C21H16N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
