Methyl (8Z,11Z,14Z,17Z)-8,11,14,17-eicosatetraenoate CAS 132712-70-0 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 Methyl (8Z,11Z,14Z,17Z)-8,11,14,17-eicosatetraenoate.

Methyl (8Z,11Z,14Z,17Z)-8,11,14,17-eicosatetraenoate (CAS 132712-70-0), molecular formula C21H34O2 and molecular weight 318.49 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl (8Z,11Z,14Z,17Z)-8,11,14,17-eicosatetraenoate (C21H34O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Methyl (8Z,11Z,14Z,17Z)-8,11,14,17-eicosatetraenoate 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.
