I had a look at the Alibaba site. Who orders a 10 kilo drum of 4-Methylaminophenol sulfate? What does it get used for apart from developing film?

More importantly, is what they are selling in big drums good enough for photographic purposes? iow, is it Metol?

Here's the blurb from one of them:

Perhaps a better comparison would be the cost to mix a liter of D-76 compared to buying a bag of Kodak's premixed.
