Chemical Structure
Description
As a certified reference material (CRM), Bromo-PEG5-phosphonic acid diethyl ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Bromo-PEG5-phosphonic acid diethyl ester (CAS 1446282-41-2), a certified reference material (molecular formula C16H34BrO8P, MW 465.31 g/mol) for analytical method development and quality control.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Bromo-PEG5-phosphonic acid diethyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 465.31 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.
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.
