Chemical Structure

9-Oxooctadecanoic Acid CAS 4114-74-3 chemical structure

Description

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.

9-Oxooctadecanoic Acid (CAS 4114-74-3) is a high-purity analytical reference standard with the molecular formula C18H34O3 and a molecular weight of 298.46 g/mol.

The molecular framework of 9-Oxooctadecanoic Acid (C18H34O3) is characterized by a carboxylic acid group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 9-Oxooctadecanoic Acid 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.
