Does anyone know anything anout this stuff? It is mentioned in an old text where it is placed between Pyrogallol and Glycin in activity. The Handbook of Chemistry and Physics shows it as a trade or common name of 2 bromo, 1,4 dihydroxybenzene, but you have to find that out by diligent search or accident. It occurs to me that it could be produced in the course of development by developers containing hydroquinone when bromine is released from the silver bromide.
