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 Diethyl (3-bromoprop-1-en-1-yl)phosphonate (CAS 66498-59-7), a certified reference material (molecular formula C7H14BrO3P, MW 257.06 g/mol) for analytical method development and quality control.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Diethyl (3-bromoprop-1-en-1-yl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
