Chemical Structure

Ethyl all cis-7,10,13,16,19-Docosapentaenoate CAS 119818-40-5 chemical structure

Description

CATO manufactures Ethyl all cis-7,10,13,16,19-Docosapentaenoate 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.

Ethyl all cis-7,10,13,16,19-Docosapentaenoate (CAS 119818-40-5) is a high-purity analytical reference standard with the molecular formula C24H38O2 and a molecular weight of 358.56 g/mol.

The molecular framework of Ethyl all cis-7,10,13,16,19-Docosapentaenoate (C24H38O2) 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 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.
