Description
Copper Sulphate Pentahydrate
Copper Sulphate Pentahydrate (CuSO4. 5H2O, CAS: 7758-99-8), also known as cupric sulphate or blue vitriol, is an inorganic compound widely recognized by its bright blue, translucent crystalline appearance. As a highly soluble salt in water, it serves as an indispensable source of bio-available copper (25% metallic copper content) across agricultural, industrial, water treatment, and animal nutrition sectors.
Key Benefits & Functional Applications
Agricultural Fungicide & Fertilizer: Functions as a primary active ingredient in fungicides (such as Bordeaux mixture) to control fungal diseases, blight, and mildew on crops, while serving as a soil additive to correct copper deficiencies.
Algaecide & Water Treatment: Applied in ponds, reservoirs, swimming pools, and irrigation canals to eliminate nuisance algae blooms and maintain clear water quality.
Animal Feed Additive: Utilized in livestock feed premixes to supply trace mineral requirements for healthy growth, bone development, and red blood cell formation.
Industrial & Mining Processing: Acts as an essential flotation reagent in mining for mineral extraction, a mordant in textile dyeing, an electroplating chemical, and a precursor in chemical manufacturing
