Malachite Green

Malachite Green is a synthetic organic compound classified as a triarylmethane dye. It appears as a green crystalline powder with a brilliant metallic sheen and is highly soluble in water and alcohol. While originally developed as a textile dye, Malachite Green is widely used in aquaculture, microbiology, and histology due to its antifungal, antibacterial, and staining properties. It is typically available in two forms: the oxalate and hydrochloride salts. Although effective in many industrial and biological applications, its use in food and veterinary contexts is restricted or banned in several countries due to toxicity concerns.

Solvent Oil Red 24 OSH Extra Pure

Solvent Oil Red 24 OSH Extra Pure is a bright red lipid-soluble dye widely used in biological staining, histology, and lipid analysis. Its high purity grade ensures consistent performance in laboratory and industrial applications including cosmetics and plastics. It dissolves readily in oils and organic solvents but is insoluble in water. Proper handling and storage are essential due to its suspected carcinogenicity and moderate toxicity to aquatic life.
