A soluble white compound used as a photographic developer.
A sulfate of 4-methylaminophenol (chemical formula: CH₃NHC₆H₄OH)
- ‘An earlier version of the formula published on the rec.photo newsgroup called for 2.5 grams of metol in place of the phenidone.’
- ‘As I have explained in my Print Solarization article, the best developer for the Sabatier effect is one that contains metol only.’

- ‘I made an exposure on Seagull, but to keep the contrast under control I was developing in Adam's Ansco 130 Variant, which has metol and glycin and gives a rather soft, warm rendering.’
- ‘Developing agents most readily available were metol, hydroquinone, and Phenidone.’
