Description

Compared with other compounds in its class, the molecular weight of 355.56 g/mol gives (9Z,12Z)-N-Phenyloctadeca-9,12-dienamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(9Z,12Z)-N-Phenyloctadeca-9,12-dienamide (CAS 19878-10-5), molecular formula C24H37NO and molecular weight 355.56 g/mol, is a CATO reference standard with documented purity and traceability.

(9Z,12Z)-N-Phenyloctadeca-9,12-dienamide (C24H37NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
