Chemical Structure

(R,10E,12Z)-9-Hydroxyoctadeca-10,12-dienoic acid CAS 10075-11-3 chemical structure

Description

(R,10E,12Z)-9-Hydroxyoctadeca-10,12-dienoic acid (CAS 10075-11-3), molecular formula C18H32O3 and molecular weight 296.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (R,10E,12Z)-9-Hydroxyoctadeca-10,12-dienoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.44 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (R,10E,12Z)-9-Hydroxyoctadeca-10,12-dienoic 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.
