Chemical Structure
Description
The occurrence of tert-Butyl (6-bromobenzo[b]thiophen-2-yl)carbamate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl (6-bromobenzo[b]thiophen-2-yl)carbamate (CAS 1909336-89-5), molecular formula C13H14BrNO2S and molecular weight 328.22 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl (6-bromobenzo[b]thiophen-2-yl)carbamate (C13H14BrNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), tert-Butyl (6-bromobenzo[b]thiophen-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.
