(5Z,8Z)-icosa-2,5,8-trienoic acid CAS 90105-02-5 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.

CATO supplies (5Z,8Z)-icosa-2,5,8-trienoic acid (CAS 90105-02-5), a certified reference material (molecular formula C20H34O2, MW 306.48 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, (5Z,8Z)-icosa-2,5,8-trienoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.48 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.

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.
