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.
Ethyl 4-(diethoxyphosphoryl)butanoate (CAS 2327-69-7) is a high-purity analytical reference standard with the molecular formula C10H21O5P and a molecular weight of 252.24 g/mol.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 4-(diethoxyphosphoryl)butanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
