Chemical Structure

Ethyl Hexanoate-d11 CAS 2159-19-5 chemical structure

Description

Structurally, Ethyl Hexanoate-d11 (C8H5D11O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 155.28 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Ethyl Hexanoate-d11 (CAS 2159-19-5), molecular formula C8H5D11O2 and molecular weight 155.28 g/mol, is a CATO reference standard with documented purity and traceability.

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.
