Physical properties
Strontium chloride Anhydrous has the formula SrCl2 and the molecular weight of 247.43 g/cm3. 
Strontium Chloride Anhydrous is a typical salt, forming neutral aqueous solutions.
Strontium chloride Anhydrous can be prepared by treating strontium hydroxide or strontium carbonate with hydrochloric acid:
Sr(OH)2+ 2HCl→SrCl2+ 2H2O
SrCO3+ 2HCl→SrCl2+ CO2+H2O
Crystallization from a cold aqueous solution gives the hexahydrate, SrCl2·6H2O. 
Dehydration of this salt occurs in stages, commencing above 61°C and ending at 320°C, where full dehydration occurs. 
The dihydrate, SrCl2·2H2O, is a metastable form before the anhydrate begins to form at 200°C. 
The hydrates formed in solution have one, two or six waters of crystallization.
SrCl2·6H2O is a hexagonal system consisting of colorless long-needle crystals. 
Strontium Chloride Anhydrous loses four crystal waters of hydration at 61.4°C to form plate crystals of SrCl2·2H2O which become the monohydrate at 100°C and anhydrate at 200°C.
Another common hydrate, SrCl2·2H2O, is composed of white, crystalline needles which have a sharp, bitter taste. 
Strontium Chloride Anhydrous can be prepared by fusing SrCO3 with CaCl2 at high temperature and then extracting the melt with water. 
The solution is then concentrated and then crystallized to form SrCl2·6H2O, which is then dehydrated at 68°C to form the dihydrate.
Anhydrous strontium chloride is a colorless crystal or a white powder with a molecular weight of 158.53 g/mol and a density of 3.05 g/cm3. Its melting point is 875°C and its boiling point is 1250°C. 
Strontium Chloride Anhydrous is easily soluble in water but slightly soluble in anhydrous alcohol and acetone. 
Strontium Chloride Anhydrous is not soluble in liquid ammonia.

Uses:
Strontium chloride Anhydrous is the precursor to other compounds of strontium, such as yellow SrCrO4, which is used as a corrosion inhibitor for aluminum.

Strontium chloride (SrCl2) is a salt of strontium and chloride. 
Strontium Chloride Anhydrous is a typical salt, forming neutral aqueous solutions. 
Like all compounds of Sr, this salt emits a bright red color in a flame; in fact it is used as a source of redness in fireworks. 
Its chemical properties are intermediate between those for barium chloride, which is more toxic, and calcium chloride.

Strontium chloride Anhydrous is the precursor to other compounds of strontium, such as yellow strontium chromate, strontium carbonate, and strontium sulfate. 
Exposure of Strontium chloride Anhydrous to the sodium salt of the desired anion (or alternately carbon dioxide gas to form the carbonate) leads to precipitation of the salt:

SrCl2 + Na2CrO4 → SrCrO4 + 2 NaCl
SrCl2 + Na2CO3 → SrCO3 + 2 NaCl
SrCl2 + H2O + CO2 → SrCO3 + 2 HCl
SrCl2 + Na2SO4 → SrSO4 + 2 NaCl

Strontium chloride Anhydrous is often used as a red coloring agent in pyrotechnics. 
Strontium chloride Anhydrous imparts a much more intense red color to the flames than most other alternatives. 
Strontium chloride Anhydrous is employed in small quantities in glass-making and metallurgy. 
The radioactive isotope strontium-89, used for the treatment of bone cancer, is usually administered in the form of strontium chloride. 
Sea water aquaria require small amounts of strontium chloride, which is consumed in the production of the exoskeletons of certain plankton.

Dental care
Strontium chloride Anhydrous is useful in reducing tooth sensitivity by forming a barrier over microscopic tubules in the dentin containing nerve endings that have become exposed by gum recession. 
Known in the U.S. as Elecol and Sensodyne, these products are called "strontium chloride toothpastes", although most now use potassium nitrate instead which works as a nerve calming agent rather than a barrier.

Biological research
Brief strontium chloride exposure induces parthenogenetic activation of oocytes which is used in developmental biological research.

Properties:
Colorless cubic crystal.Relative density 3.052.
Melting point 875ºC,Boiling point 1250ºC.

Strontium Chloride Anhydrous is also use to produce fireworks and dental care products.

Formula and structure: The strontium chloride chemical formula is SrCl2 and it has two forms: the anhydrous and the hydrated form. 
The anhydrous molar mass is 158.53 g mol-1, while 266.62 g mol-1 is the molar mass of the hexahydrate form. 
In general, the molecule is formed by a strontium cation Sr+2 and two chloride anion Cl-1 which form an structure octahedral with six anions surrounded a cation.
