The occurrence of (2S,3R)-2-((2Z,5Z)-Octa-2,5,7-trien-1-yl)-3-undecyloxirane 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.
(2S,3R)-2-((2Z,5Z)-Octa-2,5,7-trien-1-yl)-3-undecyloxirane (CAS 119072-10-5) is a high-purity analytical reference standard with the molecular formula C21H36O and a molecular weight of 304.51 g/mol.
(2S,3R)-2-((2Z,5Z)-Octa-2,5,7-trien-1-yl)-3-undecyloxirane (C21H36O) contains a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2S,3R)-2-((2Z,5Z)-Octa-2,5,7-trien-1-yl)-3-undecyloxirane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
