Useful:

• Chemical Classes: Other Classes -> Halogenated Polyaromatics
• Canonical SMILES: C1=CC=C(C=C1)C(C2=CC=CC=C2)Br
• Uses: Benzhydryl Bromide is used as a reagent in the synthesis of O-(triazolyl)methyl carbamates as a novel and potent class of fatty acid amide hydrolase (FAAH) inhibitors. Benzhydryl bromide is a halogenated building block. Benzhydryl group was preferred to the commoner benzyl to protect 2-nitrophenol in the Bartoli (vinyl Grignard) synthesis of 7-hydroxyindole. Protection was by reaction with the phenol in the presence of potassium carbonate in acetone; deprotection of the indole was by hydrogenolysis.
