4-Methylaminophenol sulfate Chemical Properties,Uses,Production
Description
Metol is contained in black-and-white film developers and caused contact dermatitis in photographers.
Chemical Properties
White crystalline powder
Uses
Photographic developer; dyeing furs.
Uses
4-(Methylamino)phenol sulfate is a photographic developer used in black and white photography. It is also used as tone developers in developing agents. Further, it is used in oxidative hair dye formulations.
Uses
Metol is a black-and-white photographic developer; dyeing furs; as pigment in hair dyes.
Uses
4-methylaminophenol sulfate is used as a photographic developer and fur dye.
Definition
ChEBI: The sulfate salt of 4-methylaminophenol.
General Description
Off-white crystalline solid. Sensitive to light.
Air & Water Reactions
Water soluble.
Reactivity Profile
In aqueous solution behaves as an acid. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Hazard
Eye and skin irritant.
Fire Hazard
Flash point data for 4-Methylaminophenol sulfate are not available but 4-Methylaminophenol sulfate is probably combustible.
Contact allergens
Metol is contained in black and white film developers and caused contact dermatitis in photographers.
Purification Methods
Crystallise this photographic developer from H2O (needles m 250-260o) (its solubility is 5% at 20o and 17% at 100o) or MeOH. It is used for determining Ag. [Palit et al. Indian J Chem, Sect B 28 64 1989.]
