Chemical Structure
Description
CATO supplies Bromo-PEG2-phosphonic acid (CAS 1446282-44-5), a certified reference material (molecular formula C6H14BrO5P, MW 277.05 g/mol) for analytical method development and quality control.
Bromo-PEG2-phosphonic acid (C6H14BrO5P) contains a carbohydrate-derived structure, a phosphate ester group, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
