I'm aware of its oxidation potential. Although I am not from a chemistry background, I do my best to use and store potentially dangerous chemicals as prescribed by their MSDS sheets. I use it for a printing-out-process called Gum Bichromate printing, and there isn't really a safer substitute sensitiser for this process that I'm aware of. The thing I'm not sure about is why I had to register with the DEA (Drug Enforcement Agency) to buy the stuff.
