Designer Drugs & Designer Smells
Currently, the perfume world is still kind of in the Middle Ages. They make "Concrete" or hash from the plant material, then they make Absolute. And this is a good process, this is how they purify things for medical use as well. If you wanted to make it even purer (like Walter White perfume) you could Isomerize it or do some Chromographic methods to get specific alkaloids or whatever you wanted.
But this is would be arbitrary, and would only bring perfume into the modern medical grade.
The way Perfume can be brought in to the FUTURE would be to make "Designer Smells" and not in the way they make smells today by mixing different absolutes, but to make NEW smells.
Here is how that would work, you could add Amino Acids to the smells, along with Baking Soda or Calcium Hydroxide. And that is just the beginning, there are ALL KINDS of different things that can be done, for example, tons of smells could be "methylated" by using methanol and an activator.
And I invented a new Smell already, but I do not have the materials to make any new smells yet. This molecule opens up the way for TONS of new Molecules. The main molecule that is in the smell of Roses is "b-Damascone", and when I was younger I heard that Anna Nicole Smith died from some drug that was like in between Xanax and Alcohol, a old school "Barbiturate" that bikers and stuff used to take. I have always been in to chemistry so I learned how it was made and it was simple, you just add Acetone and Chloroform together in the presence of Lye, and Chlorobutanol is made. This is what Anna Nicole Smith died from because she was eating it or drinking it.
But anyways. The Damascoen cane replace the Acetone, it is the same class of molecule, and then in the presence of Chloroform and Lye it would become a BRAND NEW MOLECULE with 3 open Chloride structures, which leaves the way for TONS of new things to be added.
This is only one molecule, I could make at least 10-30 new structures with Damascone if not more, and then with all the other smells I could make THOUSANDS of new smells. And so could anyone else.
