So a question for the O-Chemists out there. For developing black & white, there are a number of benzene derivatives that are important: the ones that come to mind are 1,4 dihydroxybenzene (AKA hydroquinone), 1,2 dihydroxybenzene (AKA pyrocatechin), 1,2,3 trihydroxybenzene (AKA pyrogallic acid or pyro), and apparently "Resorcin" which is I'm guessing 1,3 dyhydroxybenzene; as well, there are derivatives with chlorine and bromine that have developing properties. All of these are dangerous; some (like pyrogallic acid) are very dangerous. Despite that I am curious about the properties of other tri-oxy-benzenes (say, 1,2,4 trihydroxybenzene or something like that). Do you know anything about this or a good place to look?
