What is Calcium chloride hexahydrate CAS 7774-34-7?

Calcium chloride hexahydrate is a colorless cubic crystalline substance, commonly known as white or off white crystals in commercial products. Solubility: soluble in water and soluble in alcohol. When hexahydrate calcium chloride is heated to 30 ℃, it loses 4 crystal waters, and then continues to heat to 200 ℃ to lose all crystal waters and become anhydrous calcium chloride
