Chemical Structure
Description
The molecular framework of (S)-1-((S)-2-amino-3,3-dimethylbutanoyl)-N-(4-iodophenyl)-N-phenylpyrrolidine-2-carboxamide (C23H28IN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(S)-1-((S)-2-amino-3,3-dimethylbutanoyl)-N-(4-iodophenyl)-N-phenylpyrrolidine-2-carboxamide (CAS 371919-42-5), molecular formula C23H28IN3O2 and molecular weight 505.39 g/mol, is a CATO reference standard with documented purity and traceability.
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.
