Docosahexaenoic Acid-d5 Ethyl Ester CAS 159146-01-7

Description

The occurrence of Docosahexaenoic Acid-d5 Ethyl Ester is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Docosahexaenoic Acid-d5 Ethyl Ester (CAS 159146-01-7), molecular formula C24H31D5O2 and molecular weight 361.57 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C24H31D5O2, Docosahexaenoic Acid-d5 Ethyl Ester contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 361.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), Docosahexaenoic Acid-d5 Ethyl Ester 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.
