Chemical Structure
Description
The molecular framework of 6-[Bromoacetamido]tetramethylrhodamine (C26H24BrN3O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
6-[Bromoacetamido]tetramethylrhodamine (CAS 166442-39-3), molecular formula C26H24BrN3O4 and molecular weight 522.39 g/mol, is a CATO reference standard with documented purity and traceability.
