Hazard information
Regulatory Informationmalachite: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.
Hazards Summary
Oral LD50 (rat) of 159 mg/kg also reported; Causes somnolence, diarrhea, and normocytic anemia in oral lethal-dose studies of rats; [RTECS] Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1297-1302] A skin and strong eye irritant; Harmful by ingestion; [Sigma-Aldrich MSDS] See Copper(II) carbonate.

Applications
UsesIt can be applied to the fields of pyrotechnics, pesticides, pigments, feed, fungicides, preservatives and other industries for the manufacturing of copper compounds. It can be applied to analysis reagents and pesticides It can be applied to organic catalysts, pyrotechnics and pigments. In the field of agriculture, it can be used for the prevention of plants smut, as the poisoning antidote for insecticides and phosphorus poison antidote as well as the germicide of the seeds; being mixed with asphalt can prevent animal husbandry and wild rat from eating seedlings; it can be applied to feed as the copper additive. In the crude oil storage, it can be used as alkali agent and the raw material for the production of copper compounds. It can also be used for electroplating, corrosion and analysis reagents. It can be applied to paint color, pyrotechnics, pesticides, seed treatment germicide and for preparation of other copper salts. It can also be used as solid fluorescent powder activator.
DescriptionThis is an inorganic copper-based fungicide. It has a low aqueous solubility and a low volatility. It is highly toxic to fish and earthworms. It is moderately toxic to mammals via the oral route.
UsesUsed to kill algae and as a pigment
UsesAs seed treatment fungicide; in pyrotechnics; as paint and varnish pigment; in animal and poultry feeds; in sweetening of petrol sour crude stock; in manufacture of other Cu salts.
