Chemical Structure
Description
The molecular framework of (4-(Bromomethyl)phenyl)dimethylphosphine oxide (C9H12BrOP) is characterized by organophosphorus functionality, 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.
(4-(Bromomethyl)phenyl)dimethylphosphine oxide (CAS 2287285-08-7) is a high-purity analytical reference standard with the molecular formula C9H12BrOP and a molecular weight of 247.07 g/mol.
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), (4-(Bromomethyl)phenyl)dimethylphosphine oxide 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.
