Chemical Structure

(2-Bromoethyl)phosphonic acid CAS 999-82-6 chemical structure

Description

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.

CATO supplies (2-Bromoethyl)phosphonic acid (CAS 999-82-6), a certified reference material (molecular formula C2H6BrO3P, MW 188.95 g/mol) for analytical method development and quality control.

Structurally, (2-Bromoethyl)phosphonic acid (C2H6BrO3P) contains a phosphonate group, a carboxylic acid group, an ether linkage, bromine substitution. 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 188.95 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
