Chemical Structure
Description
Eicosapentaenoic Acid Ethyl-d5 Ester (CAS 1392217-44-5), molecular formula C22H29D5O2 and molecular weight 335.53 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Eicosapentaenoic Acid Ethyl-d5 Ester (C22H29D5O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 335.53 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
