Calcium Chloride Dihydrate (CAS 10035-04-8) is the dihydrate form of calcium chloride, a white to white-grayish crystalline salt that absorbs moisture from the air and is used in de-icing, dust suppression, concrete setting acceleration, water treatment, and as an electrolyte replenisher and firming agent in food and pharmaceuticals. It is soluble in water and ethanol, producing an exothermic solution.
