Chemical Structure

Hydroxyethylenediphosphonic Acid CAS 6851-61-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 206.03 g/mol gives Hydroxyethylenediphosphonic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Hydroxyethylenediphosphonic Acid (CAS 6851-61-2), a certified reference material (molecular formula C2H8O7P2, MW 206.03 g/mol) for analytical method development and quality control.

The molecular framework of Hydroxyethylenediphosphonic Acid (C2H8O7P2) is characterized by a phosphate ester group, a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
