12-Hydroxy-9(E)-octadecenoic acid CAS 82188-83-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 12-Hydroxy-9(E)-octadecenoic acid.

12-Hydroxy-9(E)-octadecenoic acid (CAS 82188-83-8), molecular formula C18H34O3 and molecular weight 298.46 g/mol, is a CATO reference standard with documented purity and traceability.

12-Hydroxy-9(E)-octadecenoic acid (C18H34O3) 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.
