Chemical Structure

20-Hydroxyicosanoic acid CAS 62643-46-3 chemical structure

Description

CATO supplies 20-Hydroxyicosanoic acid (CAS 62643-46-3), a certified reference material (molecular formula C20H40O3, MW 328.53 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 20-Hydroxyicosanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.53 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.

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.
