Product Overview
Calcium chloride dihydrate is a highly hygroscopic, water-soluble salt widely used in laboratories for its strong moisture-absorbing properties. This 99% pure grade ensures reliable performance in applications requiring precise dehydration, such as drying gases, liquids, or organic solvents. Its crystalline structure dissolves rapidly, making it efficient for preparing solutions or as a desiccant in closed systems. The compound’s stability under standard lab conditions and compatibility with most glassware and plastic containers further enhance its utility. Whether used in small-scale experiments or bulk processes, this reagent-grade calcium chloride dihydrate delivers consistent results without impurities that could compromise reactions. Store in a tightly sealed container to prevent moisture absorption and clumping.
FAQs
1
What is the shelf life of calcium chloride dihydrate?
When stored in an airtight container away from humidity, it remains stable for at least 2–3 years. 2
Can this be used for food-grade applications?
No, this is a lab-grade chemical and not certified for food or pharmaceutical use. 3
Is it compatible with plastic containers?
Yes, but prolonged exposure to moisture may cause corrosion; prefer glass for long-term storage. 4
What happens if it absorbs moisture?
It forms a hydrated lump but can be restored by gentle heating or re-crystallization. 5
Are there alternatives for drying solvents?
Sodium sulfate or magnesium sulfate are common alternatives, though calcium chloride is more efficient for some applications.
