Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 409.21 g/mol gives Bromo-PEG5-phosphonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Bromo-PEG5-phosphonic acid (CAS 1446282-37-6), a certified reference material (molecular formula C12H26BrO8P, MW 409.21 g/mol) for analytical method development and quality control.
The molecular framework of Bromo-PEG5-phosphonic acid (C12H26BrO8P) 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.
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.
As a certified reference material (CRM), Bromo-PEG5-phosphonic acid 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.
