Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 81276-03-1 14,15-Epoxy-5,8,11-eicosatrienoic acid 5,8,11-Tridecatrienoic acid, 13-(3-pentyloxiranyl)- 14,15-Eet 14,15-Epoxyeicosatrienoic acid 14,15-Oxido-5,8,11-eicosatrienoic acid 13-(3-Pentyloxiranyl)-5,8,11-tridecatrienoic acid.
CATO supplies 81276-03-1 14,15-Epoxy-5,8,11-eicosatrienoic acid 5,8,11-Tridecatrienoic acid, 13-(3-pentyloxiranyl)- 14,15-Eet 14,15-Epoxyeicosatrienoic acid 14,15-Oxido-5,8,11-eicosatrienoic acid 13-(3-Pentyloxiranyl)-5,8,11-tridecatrienoic acid (CAS 81276-03-1), a certified reference material (molecular formula C20H32O3, MW 320.47 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 81276-03-1 14,15-Epoxy-5,8,11-eicosatrienoic acid 5,8,11-Tridecatrienoic acid, 13-(3-pentyloxiranyl)- 14,15-Eet 14,15-Epoxyeicosatrienoic acid 14,15-Oxido-5,8,11-eicosatrienoic acid 13-(3-Pentyloxiranyl)-5,8,11-tridecatrienoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 81276-03-1 14,15-Epoxy-5,8,11-eicosatrienoic acid 5,8,11-Tridecatrienoic acid, 13-(3-pentyloxiranyl)- 14,15-Eet 14,15-Epoxyeicosatrienoic acid 14,15-Oxido-5,8,11-eicosatrienoic acid 13-(3-Pentyloxiranyl)-5,8,11-tridecatrienoic acid 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.
