Synthesis

The synthesis of 3-nitrobenzaldehyde is accomplished via nitration of benzaldehyde, which yields mostly the meta-isomer. Product distribution is about 19% for the ortho-, 72% for the meta- and 9% for the para isomers.[3]

Uses

A known use of 3-Nitrobenzaldehyde is in the synthesis of Tipranavir.

gollark: But really, I *did* do #9.
gollark: I don't know why you thought people would think it was me, apart from me repeatedly saying it was me.
gollark: 13 mod 2, which is 1, of course.
gollark: I do stupid code moderately well. This is my *thing*, and it's why I did #13.
gollark: I would NOT write code that bad.
