Synthesised and purified p-Bromoaniline

Synthesis

4-bromoaniline can be made by reacting aniline with bromine with a protection with acetyl chloride.

Applications

  1. In the synthesis of Bromamid.[3]
  2. In the synthesis of Dibromsalan (Disanyl).
gollark: That does not look like valid syntax.
gollark: Wait, what do you mean `UPDATE accounts user`?
gollark: Doesn't work *how*?
gollark: I disagree, though. Calling your thing `libbees` makes it seem like *the* one canonical library for bees, even if there is a better one available.
gollark: Yes, apparently they do go for that somewhat based on `pacman -Ss lib`.
