This is a public service announcement. To the best of my knowledge, the only place in the USA where an individual adult (as opposed to a corporation) can buy a wide selection of flavor chemicals is at:

http://shop.perfumersapprentice.com/c-88-aroma-and-flavor-molecules.aspx

I have purchased from them and they are good with prompt service and delivery.

Also, you can get information about almost any flavor chemical at:

http://www.thegoodscentscompany.com/

In particular, when using a new flavor chemical, you should look up its LD50 for rats.

Thanks, aruzinsky!

Can you explain what you mean by "its LD50 for rats"?

It is the amount per bodymass that kills half the population of rats. Ideally, one would want to know the LD50 for humans but that is rarely known. For example, according to

http://www.thegoodscentscompany.com/data/rw1008472.html (under "safety)

, the rat LD50 of methyl salicylate, a common ingredient of root beer, is 2642 mg/kg. If I want to use a similar concentration of another compound, I first check to make sure that it LD50 is not less than an order of magnitude, or I adjust the concentration accordingly. For example, before testing methyl benzoate as a substitute for methyl salicylate in root beer, I looked up its rat LD50 here

http://www.thegoodscentscompany.com/data/rw1015012.html

and found that it was 2170 mg/kg. Thus, I feel safe about using methyl benzoate at equal or less concentration than I would use methyl salicylate in root beer.
