Cupric Sulphate Anhydrous

Whatsapp Order

Cupric Sulphate Anhydrous (Copper(II) sulfate, anhydrous form) is a blue to green crystalline powder that is highly soluble in water. It is an inorganic compound consisting of copper, sulfur, and oxygen with the formula CuSO₄. Unlike its hydrated counterpart (CuSO₄·5H₂O), the anhydrous form contains no water molecules. It is widely used in agriculture, industry, and chemical manufacturing due to its fungicidal, algicidal, and chemical reactivity properties. The compound serves as a precursor to many copper salts and catalysts.

Cupric Sulphate Anhydrous Uses

Primary Uses

Agriculture

Used as a fungicide and algaecide for crops to control fungal diseases such as mildew, blight, and root rot.
Acts as a micronutrient fertilizer supplement providing copper, essential for plant metabolism and growth.
Used in animal feed as a trace mineral additive for copper deficiency prevention.

Chemical Industry

Utilized as a raw material for the manufacture of other copper compounds such as copper salts and catalysts.
Used in chemical laboratories for reagent preparation and analytical tests, including Fehling’s and Benedict’s solutions for sugar detection.
Employed as a mordant in dyeing and printing textiles.

Secondary Uses

Water Treatment

Applied as an algicide to control algae growth in water bodies, reservoirs, and industrial cooling systems.

Electroplating

Used as an electrolyte component in copper plating baths to deposit copper metal coatings.

Veterinary Medicine

Included in certain topical antiseptic and antimicrobial formulations for livestock.

Pigment Production

Acts as a pigment in ceramics, paints, and inks due to its distinctive blue color.
