Chemical Structure
Description
(S,Z)-3-Oxo-N-(2-oxotetrahydrofuran-3-yl)hexadec-11-enamide (CAS 479050-91-4) is a high-purity analytical reference standard with the molecular formula C20H33NO4 and a molecular weight of 351.48 g/mol.
(S,Z)-3-Oxo-N-(2-oxotetrahydrofuran-3-yl)hexadec-11-enamide (C20H33NO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
