Calcium chloride (anhydrous)（Cat No.:R033549）is an inorganic salt with the chemical formula CaCl₂. It appears as a white, hygroscopic solid and is highly soluble in water. Known for its strong moisture-absorbing properties, it is widely used as a desiccant in drying gases and liquids. In industrial settings, calcium chloride serves in de-icing, dust control, and concrete acceleration. It is also used in food processing, water treatment, and as a calcium supplement. Its exothermic reaction with water makes it useful in self-heating packs and other heat-generating chemical applications.
