Description
As a certified reference material (CRM), tert-Butyl 5-bromo-4-nitrothiophene-2-carboxylate 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 tert-Butyl 5-bromo-4-nitrothiophene-2-carboxylate (CAS 62224-29-7), a certified reference material (molecular formula C9H10BrNO4S, MW 308.15 g/mol) for analytical method development and quality control.
tert-Butyl 5-bromo-4-nitrothiophene-2-carboxylate (C9H10BrNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
