Chemical Structure
Description
11,12-Epoxy-(5Z, 8Z, 14Z)-eicosatrienoic acid (CAS 123931-40-8) is a high-purity analytical reference standard with the molecular formula C20H32O3 and a molecular weight of 320.47 g/mol.
11,12-Epoxy-(5Z, 8Z, 14Z)-eicosatrienoic acid (C20H32O3) 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 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.
CATO manufactures 11,12-Epoxy-(5Z, 8Z, 14Z)-eicosatrienoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
