Chemical Structure

8(Z),11(Z),14(Z),17(Z)-Octadecatetraenoic Acid Ethyl Ester CAS 2580285-53-4 chemical structure

Description

The occurrence of 8(Z),11(Z),14(Z),17(Z)-Octadecatetraenoic Acid Ethyl Ester is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 8(Z),11(Z),14(Z),17(Z)-Octadecatetraenoic Acid Ethyl Ester (CAS 2580285-53-4), a certified reference material (molecular formula C20H32O2, MW 304.47 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 8(Z),11(Z),14(Z),17(Z)-Octadecatetraenoic Acid Ethyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 8(Z),11(Z),14(Z),17(Z)-Octadecatetraenoic Acid Ethyl Ester 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.
