Chemical Structure

Cyclopentanone-2,2,5,5-d4 CAS 3997-89-5 chemical structure

Description

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.

Cyclopentanone-2,2,5,5-d4 (CAS 3997-89-5) is a high-purity analytical reference standard with the molecular formula C5H4D4O and a molecular weight of 88.14 g/mol.

Structurally, Cyclopentanone-2,2,5,5-d4 (C5H4D4O) contains deuterium isotope labeling, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 88.14 g/mol, it falls into the low-molecular-weight range. 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).

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.
