Docosahexaenoic Acid-d5 CAS 1197205-71-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Docosahexaenoic Acid-d5.

Docosahexaenoic Acid-d5 (CAS 1197205-71-2) is a high-purity analytical reference standard with the molecular formula C22H27D5O2 and a molecular weight of 333.52 g/mol.

Structurally, Docosahexaenoic Acid-d5 (C22H27D5O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 333.52 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
