Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-Butyl (2-bromo-5-fluorophenyl)carbamate (CAS 861931-75-1) is a high-purity analytical reference standard with the molecular formula C11H13BrFNO2 and a molecular weight of 290.13 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, tert-Butyl (2-bromo-5-fluorophenyl)carbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), tert-Butyl (2-bromo-5-fluorophenyl)carbamate 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.
