Chemical Structure

Octadecanoic-4,4-d CAS 62690-13-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 286.49 g/mol gives Octadecanoic-4,4-d distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Octadecanoic-4,4-d (CAS 62690-13-5) is a high-purity analytical reference standard with the molecular formula C18H34D2O2 and a molecular weight of 286.49 g/mol.

The molecular framework of Octadecanoic-4,4-d (C18H34D2O2) is characterized by deuterium isotope labeling, 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Octadecanoic-4,4-d meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
