Question

which career area in chemistry applies new discoveries to practicals applications useful for consumers .?

Answer 1

Pharmaceutical Chemistry or possibly Organic Chemistry. Those are the fields in chemistry which either design drugs or use certain drug compounds in trials to apply them for consumers.

For example, an synthetic organic chemist might design a compound such that it binds specifically to a target area in the body to say, prevent RNA synthesis, or target a particular area in a bacterial cell so that they do not reproduce and spread throughout the body.
