Most of the heavy duty brewing chemistry books I know of are really aimed at commercial brewers and may be more or less relevant to homebrewers. That said, look for "Principles of Brewing Science" by George Fix, "New Brewing Lager Beer" by Greg Noonan, "Brewing Science and Practice" by Briggs, and books by Narziss or de Clerck. Pretty heavy duty science! For something not quite as intense, check out "How to Brew" by John Palmer. These are all general brewing books. You can also get specific books that cover things like yeast or hops.
Also, don't forget "Yeast" by Chris White and Jamil Zainasheff! Great practical guide for homebrewers, but they also go into some light organic chemistry of yeast cell health, behavior, reproduction/budding, etc.
