Description
CATO supplies 2-(tert-Butyl)-4-chloro-6-fluorobenzo[d]oxazol-7-amine (CAS 650598-18-8), a certified reference material (molecular formula C11H12ClFN2O, MW 242.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-(tert-Butyl)-4-chloro-6-fluorobenzo[d]oxazol-7-amine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(tert-Butyl)-4-chloro-6-fluorobenzo[d]oxazol-7-amine 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.
