Chemical Structure
Description
The occurrence of (6E,8Z)-5-Oxo-6,8-octadecadienoic Acid 1021188-25-9 5-Oxo-(6E,8Z)-octadecadienoic Acid 5-oxo-ODE is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(6E,8Z)-5-Oxo-6,8-octadecadienoic Acid 1021188-25-9 5-Oxo-(6E,8Z)-octadecadienoic Acid 5-oxo-ODE (CAS 1021188-25-9), molecular formula C18H30O3 and molecular weight 294.43 g/mol, is a CATO reference standard with documented purity and traceability.
(6E,8Z)-5-Oxo-6,8-octadecadienoic Acid 1021188-25-9 5-Oxo-(6E,8Z)-octadecadienoic Acid 5-oxo-ODE (C18H30O3) contains a steroid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
