Hazard Information

Chemical Properties

green crystals

Uses

A triphenylmethane dye with fungicidal and limited antiseptic activity. The term Malachine green applies to the oxalate as well as the chloride. Harmful if swallowed. Avoid release to the environment.

Definition

ChEBI: An organic chloride salt that is the monochloride salt of malachite green cation. Used as a green-coloured dye, as a counter-stain in histology, and for its anti-fungal properties in aquaculture.

General Description

Green crystals with metallic luster. Water solutions are blue-green. Used in dyeing silk, wool, biological staining, etc.

Air & Water Reactions

Very soluble in water.

Reactivity Profile

Pigment Green 18 neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Hazard

Toxic by ingestion.

Preparation

commonly known as Malachite Green. (a) in the presence of hydrochloric acid or sulfuric acid, Benzaldehyde ?(1 Moore) and N,N-dimethylaniline(2 Moore) condensation, and then used lamps and acid oxidation its products; (b) N,N-dimethylaniline and 1-(Trichloromethyl)benzene?heating.
