Chemical Structure

Phosphoric Acid Diethyl Ester CAS 598-02-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phosphoric Acid Diethyl Ester.

Phosphoric Acid Diethyl Ester (CAS 598-02-7) is a high-purity analytical reference standard with the molecular formula C4H11O4P and a molecular weight of 154.10 g/mol.

Structurally, Phosphoric Acid Diethyl Ester (C4H11O4P) contains a carbohydrate-derived structure, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 154.10 g/mol, it falls into the medium-molecular-weight range.

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.
