Description
As a certified reference material (CRM), 7-Bromo-2-(((tert-butyldimethylsilyl)oxy)methyl)-2-methyl-2,3-dihydropyrazolo[5,1-b]oxazole 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.
CATO supplies 7-Bromo-2-(((tert-butyldimethylsilyl)oxy)methyl)-2-methyl-2,3-dihydropyrazolo[5,1-b]oxazole (CAS 2894830-88-5), a certified reference material (molecular formula C13H23BrN2O2Si, MW 347.32 g/mol) for analytical method development and quality control.
7-Bromo-2-(((tert-butyldimethylsilyl)oxy)methyl)-2-methyl-2,3-dihydropyrazolo[5,1-b]oxazole (C13H23BrN2O2Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
