Diethyl (3-hydroxypropyl)phosphonate CAS 55849-69-9

Description

The occurrence of Diethyl (3-hydroxypropyl)phosphonate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Diethyl (3-hydroxypropyl)phosphonate (CAS 55849-69-9), molecular formula C7H17O4P and molecular weight 196.18 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Diethyl (3-hydroxypropyl)phosphonate (C7H17O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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 196.18 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.
