Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Phosphorobromidic acid (CAS 25758-00-3), a certified reference material (molecular formula H2BrO3P, MW 160.89 g/mol) for analytical method development and quality control.
Phosphorobromidic acid (H2BrO3P) 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.
As a certified reference material (CRM), Phosphorobromidic 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.
