That it is the hemisulfate is part of a note that I made in one of my notebooks
years ago. Sorry I didn't list a source at that time. The remaining part of
the note is that Kodelon is paraminophenol hemioxalate.

What is the source for this identification of Gradol? The booklet "The Edwal
Professional Photographers' Manual" that I have identifies it as "a derivative
of para aminophenol" without being more specific.
