(6E,8Z,11Z,14Z)-5-Hydroxy-6,8,11,14-eicosatetraenoic acid CAS 71030-39-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(6E,8Z,11Z,14Z)-5-Hydroxy-6,8,11,14-eicosatetraenoic acid (CAS 71030-39-2) is a high-purity analytical reference standard with the molecular formula C20H32O3 and a molecular weight of 320.47 g/mol.

The molecular framework of (6E,8Z,11Z,14Z)-5-Hydroxy-6,8,11,14-eicosatetraenoic acid (C20H32O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
