Chemical Structure
Description
3-(4-Hydroxy-2-methylanilino)-2-phenyl-1H-inden-1-one (CAS 1023497-27-9), molecular formula C22H17NO2 and molecular weight 327.38 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Hydroxy-2-methylanilino)-2-phenyl-1H-inden-1-one (C22H17NO2) contains a steroid core, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
