A dihalogenated aniline building block

Used as a synthesis intermediate for APIs

Specifications | MSDS | Literature and Reviews

5-Bromo-4-fluoro-2-methylaniline (CAS number 627871-16-3) is derived from 2-methylaniline with fluoride and bromide substituents at the 4- and 5-positions. 5-Bromo-4-fluoro-2-methylaniline possesses multiple reactivities, including cross-coupling reactions on the bromide substituent, nucleophilic substitution on the amine, and nucleophilic aromatic substitution on the fluoride group.

5-Bromo-4-fluoro-2-methylaniline is one of the key ingredients for the synthesis of MDL compounds (N-phenyl-4-(phenylsulfonamido)benzenesulfonamide derivatives, MDL-800, MDL-801 and MDL-811). MDL compounds are activators of sirtuin 6 (SIRT6), a lysine deacetylase that acts as a tumour suppressor. MDL compounds increase the deacetylase activity of SIRT6 by binding to an allosteric site, leading to a decrease in histone levels in human hepatocellular carcinoma cells.
