Product Overview & Quality

Product Name: Copper (II) sulfate anhydrous
Brand: Kemaus (Product Code: KA-1007)
Grade: Laboratory Grade (Lab Grade) with a high purity of 99 percent or higher. Carefully processed under Kemaus production quality control to ensure an entirely moisture-free crystal structure. Highly relied upon for unique testing protocols and moisture-sensitive applications.
Physical Properties: Odorless, fine white to pale greyish-white powder.
Key Characteristic: Extremely sensitive to moisture. Upon contacting water or ambient moisture, it undergoes an exothermic reaction (releases heat) and immediately undergoes a dramatic visual transformation from a white powder to a vibrant blue compound.
Key Use: Widely utilized as an analytical reagent for the detection of trace water or moisture content in organic solvents and absolute alcohols. Functions as an effective desiccant (drying agent) in moisture-free chemical synthesis. Also applied as a chemical precursor for preparing various testing reagents, including Benedict’s and Fehling’s solutions.

Safety & Hazards (Critical)

Classification: Harmful if swallowed. Causes skin irritation. Causes serious eye irritation.
Health Risks: Ingestion leads to acute copper toxicity, causing severe gastrointestinal discomfort, nausea, and vomiting. Direct skin or eye contact causes chemical irritation and redness, potentially enhanced by the thermal effect generated upon meeting moisture on body tissues.
Environmental Hazards: Very toxic to aquatic life with long-lasting effects. Strict hazardous chemical disposal guidelines apply. Do not discharge into general sewers.
First Aid Measures: Immediately flush affected eyes or skin with plenty of flowing water for at least 15 minutes. If swallowed, rinse mouth thoroughly with water and seek immediate medical attention.

Handling & Storage

Storage: Highly Hygroscopic. It rapidly and aggressively absorbs water vapor from surrounding air. Must be stored in the original, tightly sealed Kemaus container. Keep in a strictly dry, cool, and well-ventilated location at stable room temperature (below 30 degrees Celsius). Never leave the container open, as exposure to ambient air will ruin the anhydrous properties and turn the powder blue.
Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a particulate dust respirator. Avoid handling in high-humidity environments.
