Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 7-oxo-7-[3-(pyrrolidinomethyl)phenyl]heptanoate.
Ethyl 7-oxo-7-[3-(pyrrolidinomethyl)phenyl]heptanoate (CAS 898771-10-3), molecular formula C20H29NO3 and molecular weight 331.45 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 7-oxo-7-[3-(pyrrolidinomethyl)phenyl]heptanoate (C20H29NO3) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
