Chemical Structure

Octadecanoic-17,17,18,18,18-d5 Acid CAS 211443-83-3 chemical structure

Description

Octadecanoic-17,17,18,18,18-d5 Acid (CAS 211443-83-3) is a high-purity analytical reference standard with the molecular formula C18H31D5O2 and a molecular weight of 289.51 g/mol.

Based on its molecular formula C18H31D5O2, Octadecanoic-17,17,18,18,18-d5 Acid contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 289.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-17,17,18,18,18-d5 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.
