An introduction to NBS (N-bromo succinimide) as a reagent in organic chemistry — Master Organic Chemistry In a blatant plug for the Reagent Guide, each Friday I profile a different reagent that is commonly encountered in Org 1/ Org 2. If you’ve ever had the “pleasure” of working with bromine (Br 2 ), you’ll know th at this dense orange liquid is a pain in the butt for two reasons. First of all, it fumes like a bastard . Once you open the bottle, orange fumes start spewing everywhere, and if you haven’t put the bottle deep into the fume hood, you will soon be savoring the unforgettable aroma of Br2 (mixed with HBr) in your nostrils. Secondly, it’s extreme ly dense (d=3.19) and therefore drops of it tend t o fall from whatever you’re using to dispense it with, Jackson Pollock style, leaving little violently fuming orange puddles behind. In contrast, NBS (N-bromo succinimide) is a gleaming white crystalline solid and easy as pie to work with. But don’t be deceived. It packs a punch.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
