Chemical Structure
Description
The occurrence of 9-hydroxy-10E,12Z-octadecadienoic Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
9-hydroxy-10E,12Z-octadecadienoic Acid (CAS 98524-19-7) is a high-purity analytical reference standard with the molecular formula C18H32O3 and a molecular weight of 296.44 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 9-hydroxy-10E,12Z-octadecadienoic 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 9-hydroxy-10E,12Z-octadecadienoic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
