10043-52-4 Usage


Calcium chloride is highly hygroscopic and is often used as a desiccant.

Air & Water Reactions

Deliquescent. Water soluble. Adding Calcium chloride to hot water caused violent boiling, [MCA Case History No. 69].

Chemical Properties

Calcium chloride, CaC12, is colorless deliquescent solid that is soluble in water and ethanol. It is formed from the reaction of calcium carbonate and hydrochloric acid or calcium hydroxide and ammonium chloride. It is used in medicine, as an antifreeze, and as a coagulant.

Reactivity Profile

Bromine trifluoride rapidly attacks the following salts: barium chloride, cadmium chloride, Calcium chloride, cesium chloride, lithium chloride, silver chloride, rubidium chloride, potassium bromide, potassium chloride, potassium iodide, rhodium tetrabromide, sodium bromide, sodium chloride, and sodium iodide [Mellor 2 Supp. 1:164, 165 1956]. Long term exposure of Calcium chloride solution upon a zinc coated galvanized iron vessel caused slow evolution of hydrogen which ignited and exploded [Bretherick, 5th Ed., 1995].


For the treatment of hypocalcemia in those conditions requiring a prompt increase in blood plasma calcium levels, for the treatment of magnesium intoxication due to overdosage of magnesium sulfate, and used to combat the deleterious effects of hyperkalemi

Health Hazard

Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes (particularly by dust) causes irritation and possible transient corneal injury. Contact of solid with dry skin causes mild irritation; strong solutions can cause marked irritation, even a superficial burn.

Purification Methods

It is available as fused granules or cubic crystals. It is very hygroscopic, very soluble in H2O (exothermic), and EtOH. Store it in a tightly closed container. [Ehrlich in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 931 1963.]

General Description

White to off-white solid. Sinks and mixes with water.


Anhydrous calcium chloride is commonly used in industrial production and laboratories as a dehydrating and drying agent; it is mainly used to dry gases (nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, etc., but not ammonia, hydrogen sulfide and alcohol), petroleum, organic solvents, etc. It is used as a dehydrating agent in the production of alcohols, esters, ethers and acrylic resins.
In inorganic industries, it is a raw ingredient in producing metallic calcium and various calcium salts. It is used as a protecting and refining agent for aluminum magnesium metallurgy. It is used to remove ink in waste paper processing.
It is also used as a sizing agent and fire retardant in textile production, as well as a fog-clearing agent in harbors, dust collector for roads, water purifier, food preservative, and road cleanser. It is a precipitant in producing lake colored pigments.
CaCl2•6H2O mixed with ice at a 1.44:1 ratio is used in laboratories as a cryogen, which can achieve -54.9℃ temperatures. Calcium chloride solution is an important cryogen in freezers and ice production, and it can speed up the hardening of cement and fortify building motar against cold weather, making it an excellent antifreeze for buildings.
It is also used to treat symptoms of low blood calcium such as tetany, urticaria, exudative edema, colic and ureteral colic, magnesium poisoning, etc. In the food industry,  it is used as a calcium strengthener, hardening agent, chelating agent, and drying agent.
It can also test for the carbon content of steel, and it can test the vitality of blood sugar, serum phosphorous, serum alkaline phosphatase.


It is highly hygroscopic and is often used as a desiccant.

Brand name

Cal Plus (Mallinckrodt).


LD50 4 g/kg (Large mice, oral). ADI has not regulations. Generally approved to be safe (USFDA)
Will erode skin upon contact and causes welts. Wear protective clothing, gloves, and tall boots when producing and transporting, and protect skin.
