What is metol?

[Peter Speck]

This may seem a silly Q., but does anyone know the chemical formula for
metol? I've looked in a few chemical company catalogues and in the Merck
index and there's nothing of that name listed.

Metol is a brand name of a developer like Coke is to soda pop.
The chemical name is P-methylaminophenol sulfate. Kodak's
brand name is Elon. Metol itself will process film at a low
contrast. Developer life is short and the film will have heavy
grain without the addition of Sodium Sulfite. The mixture of
7 grams of Metol with 90 grams of sodium sulfite to one qt water
is called Kodak brand D-23 low contrast developer. Process 5min
at 70 degrees with Tri-x film. Great negs!!!.

It should be cross-reference in the back of the Merck Index. It is:

p-methylaminophenol sulfate
monomethyl-p-aminophenol sulfate
p-hydroxymethylaniline sulfate

aka Elon, Photol, Verol, Rhodol, Armol, Genol, Graphol,
Photo-Rex,Pictol, and Planetol.

I use my own nomenclature, and call it N-methyl-p-aminophenol sulfate.
