Compared with other compounds in its class, the molecular weight of 320.45 g/mol gives Sodium ricinoleate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sodium ricinoleate (CAS 5323-95-5) is a high-purity analytical reference standard with the molecular formula C18H33O3Na and a molecular weight of 320.45 g/mol.
Sodium ricinoleate (C18H33O3Na) contains a carboxylic acid 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
