Chemical Structure

2-(Diethoxyphosphoryl)pentanoic acid CAS 84589-96-8 chemical structure

Description

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(Diethoxyphosphoryl)pentanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

2-(Diethoxyphosphoryl)pentanoic acid (CAS 84589-96-8), molecular formula C9H19O5P and molecular weight 238.22 g/mol, is a CATO reference standard with documented purity and traceability.

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.
