Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, Tert-butyl 4-(5-bromo-1,3,4-thiadiazol-2-yl)-1,4-diazepane-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.27 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).
Tert-butyl 4-(5-bromo-1,3,4-thiadiazol-2-yl)-1,4-diazepane-1-carboxylate (CAS 1357147-44-4), molecular formula C12H19BrN4O2S and molecular weight 363.27 g/mol, is a CATO reference standard with documented purity and traceability.
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), Tert-butyl 4-(5-bromo-1,3,4-thiadiazol-2-yl)-1,4-diazepane-1-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.
