Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (8Z,11Z,14Z)-Octadecatrienoic Acid Ethyl Ester.
CATO supplies (8Z,11Z,14Z)-Octadecatrienoic Acid Ethyl Ester (CAS 2347415-30-7), 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, (8Z,11Z,14Z)-Octadecatrienoic Acid Ethyl Ester 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.
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 (8Z,11Z,14Z)-Octadecatrienoic 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.
