Chemical Structure

Dimethyl(4-carboxybutyl)phosphonate CAS 959580-89-3 chemical structure

Description

Dimethyl(4-carboxybutyl)phosphonate (CAS 959580-89-3), molecular formula C7H15O5P and molecular weight 210.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dimethyl(4-carboxybutyl)phosphonate (C7H15O5P) 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 210.16 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.
