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.
Ethyl 8-oxo-8-[2-(3-pyrrolinomethyl)phenyl]octanoate (CAS 898764-04-0), molecular formula C21H29NO3 and molecular weight 343.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 8-oxo-8-[2-(3-pyrrolinomethyl)phenyl]octanoate (C21H29NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
