Questions and Answers (Q&A) | Back Directory | [Description]
Strontium is the inorganic salt consisting of strontium and chloride. In organic synthesis, it can be used as the resource for the manufacturing of other kinds of strontium compound. It can also be used to reduce the tooth sensitivity through covering the microscopic tubules in the dentin with nerve endings which has been exposed to gum recession. It can be further used as a red coloring agent in pyrotechnics. Recent study has also shown that a novel topical formulation containing strontium chloride can effectively reduce the intensity and duration of cowhage-induced itch. In biological research, it has been successfully used to induce activation of mouse oocytes in nuclear transfer and other experiments, which is important in understanding the mechanisms of fertilization and early embryonic development.

Hazard Information | Back Directory | [Chemical Properties]
Strontium chloride, SrCl2 is a salt of strontium and chlorine. It is ionic and water-soluble. It is less toxic than barium chloride [CAS: 10361-37-2] BaCl2, though more toxic than calcium chloride CaCl2. It emits a bright red color when heated in a flame. Strontium chloride can be prepared from strontium hydroxide or strontium carbonate reacting with hydrochloric acid. It can also be prepared by the union of the elements, strontium and chlorine. | [Chemical Properties]
White crystalline powder | [Physical properties]
Strontium chloride has the formula SrCl2 and the
molecular weight of 247.43 g/cm3. It is a typical salt, forming neutral aqueous solutions.
Strontium chloride 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. It 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. It 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. It is easily soluble
in water but slightly soluble in anhydrous alcohol and acetone. It is not soluble in liquid ammonia. | [Definition]
strontium chloride: A white compound, SrCl2. The anhydrous salt (cubic; r.d. 3.05; m.p. 872°C; b.p. 1250°C) can be prepared by passing chlorine over heated strontium. It is deliquescent and readily forms the hexahydrate, SrCl2·6H2O (r.d. 2.67).This can be made by neutralizing hydrochloric acid with strontium carbonate, oxide, or hydroxide. Strontium chloride is used for military flares. | [Preparation]
Strontium chloride is obtained by dissolving strontium carbonate in concentrated hydrochloric acid. The hexahydrate, SrCl2 · 6H2O [10025-70-4], is formed on crystallizing below 61℃. On dehydration, the hexahydrate dissolves in its water of crystallization at 61℃. After passing through the di- and monohydrate stages, strontium chloride becomes fully dehydrated at 320℃. | [Brand name]
Stronscan-85 (Abbott). | [General Description]
Strontium chloride hexahydrate (SrCl2·6H2O) is a hydrated alkaline earth metal chloride. On γ-irradiation at 77°K, it affords a radical having e.s.r. parameters resembling with HO2. Its chlorine electric field gradient (EFG) and chemical shift (CS) tensors have been evaluated by employing solid-state 35/37Cl NMR spectroscopy. |
