Chemical Structure

Octadecanoic Acid Ethyl Ester CAS 111-61-5 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Octadecanoic Acid Ethyl Ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.53 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.

CATO supplies Octadecanoic Acid Ethyl Ester (CAS 111-61-5), a certified reference material (molecular formula C20H40O2, MW 312.53 g/mol) for analytical method development and quality control.

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 Octadecanoic 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.
