Chemical Structure
Description
The occurrence of tert-Butyl 4-bromo-2-iodobenzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl 4-bromo-2-iodobenzoate (CAS 944276-64-6), molecular formula C11H12BrIO2 and molecular weight 383.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 4-bromo-2-iodobenzoate (C11H12BrIO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system. 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.
