Ethyl 7-[4-(N,N-dimethylamino)phenyl]-7-oxoheptanoate (CAS 91727-04-7), molecular formula C17H25NO3 and molecular weight 291.39 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 7-[4-(N,N-dimethylamino)phenyl]-7-oxoheptanoate (C17H25NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
