Copper;sulfate;pentahydrate

Copper sulfate pentahydrate is an inorganic crystalline compound with the chemical formula CuSO4·5H2O (CAS: 7758-99-8). This blue crystalline salt contains five molecules of water of crystallization per copper sulfate unit, giving it a molecular weight of 249.69 g/mol. It is one of the most common copper compounds used in industry and is classified as a hazardous substance requiring careful handling due to its toxicity and environmental impact.

Copper sulfate pentahydrate appears as bright blue crystals or crystalline powder at room temperature. It is highly soluble in water, producing a characteristic blue solution, and has no distinct odor. The compound is stable under normal conditions but loses water of crystallization when heated, transforming into the anhydrous white form. It has a density of approximately 2.286 g/cm³ and decomposes at temperatures above 200°C.

Copper sulfate pentahydrate serves multiple industrial and agricultural purposes. It is primarily used as a fungicide in agriculture, for electroplating and metal finishing processes, and as a catalyst in various chemical reactions. Additionally, it finds applications in water treatment as an algaecide, in the production of other copper compounds, textile dyeing, leather processing, and as a laboratory reagent for analytical chemistry and educational purposes.

Copper sulfate pentahydrate requires careful handling using appropriate personal protective equipment including safety goggles, gloves, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas to avoid inhalation of dust particles. Avoid eating, drinking, or smoking during handling. Wash hands thoroughly after use and ensure emergency eyewash stations are accessible. The substance is classified as Acute Tox. 4 and Eye Dam. 1, requiring strict adherence to safety protocols.

Copper sulfate pentahydrate should be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, aluminum, and magnesium. Keep containers tightly closed and protect from moisture to prevent caking. Store away from food, beverages, and animal feed. Ensure storage areas are equipped with appropriate spill containment measures and maintain temperatures below 30°C to preserve product stability and prevent decomposition.

Copper sulfate pentahydrate contact requires immediate action. For eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention due to its Eye Dam. 1 classification. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air immediately. If ingested, rinse mouth and seek medical attention without inducing vomiting. Always consult a physician in case of exposure and provide the safety data sheet.

Copper sulfate pentahydrate disposal must comply with local environmental regulations due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications. Never dispose of it down drains or into water systems. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities may require neutralization before disposal. Contaminated packaging should also be treated as hazardous waste. Always consult local authorities for specific disposal requirements in your region.

Copper sulfate pentahydrate is classified under ADR Class 6.1 (toxic substances), Packing Group III for transportation. It requires appropriate hazardous material packaging, labeling with GHS07, GHS05, and GHS09 pictogrammes, and documentation including transport documents. Vehicles must display proper placards and drivers need hazardous materials training. Ensure packages are secure, undamaged, and protected from moisture during transit while following all applicable dangerous goods regulations.

Copper sulfate pentahydrate is subject to multiple regulatory frameworks including REACH registration requirements in Europe and CLP classification as Acute Tox. 4, Eye Dam. 1, Aquatic Acute 1, and Aquatic Chronic 1. It requires safety data sheets, proper labeling with 'Danger' signal word, and compliance with occupational exposure limits. While not currently listed as SVHC, its environmental toxicity makes it subject to strict usage and disposal regulations across European jurisdictions.
