Chemical Structure
Description
(bromomethyl)phosphonic acid (CH4BrO3P) contains a phosphonate group, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point; 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.
(bromomethyl)phosphonic acid (CAS 7582-40-3), molecular formula CH4BrO3P and molecular weight 174.92 g/mol, is a CATO reference standard with documented purity and traceability.
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), (bromomethyl)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.
