Chemical Structure
Description
The molecular framework of Bromo-PEG3-phosphonic acid diethyl ester (C12H26BrO6P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies Bromo-PEG3-phosphonic acid diethyl ester (CAS 1148026-98-5), a certified reference material (molecular formula C12H26BrO6P, MW 377.21 g/mol) for analytical method development and quality control.
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.
