Chemical Structure
Description
1-(3-Methoxyphenyl)-3-(3-phenylpyrrolidin-1-yl)propan-1-one (CAS 426243-78-9), molecular formula C20H23NO2 and molecular weight 309.40 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Methoxyphenyl)-3-(3-phenylpyrrolidin-1-yl)propan-1-one (C20H23NO2) 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 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.
