Pyridinium Tribromide is used as a brominating agent for organic synthesis especially for pharmaceuticals and hormones. It can be replaced for n-Bromosuccinimide. (N-Bromo derivatives and ammonium tribromides are mainly used as brominating agents)
Top definition. Vlad. Vlad is usually a Russian name, sometimes romanian, and usually is an athletic all around great guy that is good at everything. He is known to have a big penis and is a legend in bed. He has an amazing body and really funny. He is very popular especially with females...fine females.
Why do Romanians think Vlad the Impaler was a Good Guy? In my survey of the Top Ten Evil people in history, I list Vlad the Impaler as Number 2. Interestingly, every Romanian I talked to thought Vlad the Impaler should be removed from the Evil list because they view him as good and not evil.
