4-Methylaminophenol sulfate Chemical Properties,Usage,Production

Description

Metol is contained in black-and-white film developers and caused contact dermatitis in photographers.

Chemical Properties

White crystalline powder

Uses

Metol is a black-and-white photographic developer; dyeing furs; as pigment in hair dyes.

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

4-methylaminophenol sulfate is used as a photographic developer and fur dye.

Uses

Photographic developer; dyeing furs.

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.]
