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 (7-chloro-4-iodobenzo[d]thiazol-2-yl)carbamate (CAS 2803283-90-9), molecular formula C12H12ClIN2O2S and molecular weight 410.66 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, tert-Butyl (7-chloro-4-iodobenzo[d]thiazol-2-yl)carbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 410.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), tert-Butyl (7-chloro-4-iodobenzo[d]thiazol-2-yl)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.
