CATO supplies 76792-22-8 IS538QCW8W alpha-Bromoisovaleric acid, (R)- Butanoic acid, 2-bromo-3-methyl-, (2R)- UNII-IS538QCW8W (CAS 76792-22-8), a certified reference material (molecular formula C5H9BrO2, MW 181.03 g/mol) for analytical method development and quality control.
76792-22-8 IS538QCW8W alpha-Bromoisovaleric acid, (R)- Butanoic acid, 2-bromo-3-methyl-, (2R)- UNII-IS538QCW8W (C5H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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), 76792-22-8 IS538QCW8W alpha-Bromoisovaleric acid, (R)- Butanoic acid, 2-bromo-3-methyl-, (2R)- UNII-IS538QCW8W 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.
