Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
8-hydroxy-5Z,9E,11Z,14Z-eicosatetraenoic Acid (CAS 79495-84-4) 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, 8-hydroxy-5Z,9E,11Z,14Z-eicosatetraenoic 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.
CATO manufactures 8-hydroxy-5Z,9E,11Z,14Z-eicosatetraenoic 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.
