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.
Diethyl (3-oxocyclopentyl)phosphonate (CAS 7750-01-8) is a high-purity analytical reference standard with the molecular formula C9H17O4P and a molecular weight of 220.20 g/mol.
Structurally, Diethyl (3-oxocyclopentyl)phosphonate (C9H17O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 220.20 g/mol, it falls into the medium-molecular-weight range.
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.
