Chemical Structure
Description
tert-Butyl (3-bromo-2,6-difluorophenyl)carbamate (CAS 721446-29-3), molecular formula C11H12BrF2NO2 and molecular weight 308.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl (3-bromo-2,6-difluorophenyl)carbamate (C11H12BrF2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
