Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S,5Z,8Z,12Z,14Z)-11-Hydroxyicosa-5,8,12,14-tetraenoic acid.
(S,5Z,8Z,12Z,14Z)-11-Hydroxyicosa-5,8,12,14-tetraenoic acid (CAS 54886-50-9) is a high-purity analytical reference standard with the molecular formula C20H32O3 and a molecular weight of 320.47 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, (S,5Z,8Z,12Z,14Z)-11-Hydroxyicosa-5,8,12,14-tetraenoic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), (S,5Z,8Z,12Z,14Z)-11-Hydroxyicosa-5,8,12,14-tetraenoic 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.
