octadecanoic acid CAS 1957-11-4

Description

Compared with other compounds in its class, the molecular weight of 284.48 g/mol gives octadecanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies octadecanoic acid (CAS 1957-11-4), a certified reference material (molecular formula C18H36O2, MW 284.48 g/mol) for analytical method development and quality control.

The molecular framework of octadecanoic acid (C18H36O2) 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.

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 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.
