The Properties, Specifications, Monograph and Uses of Tin Fluoride or Stannous Fluoride:

CAS Number: 7783-47-3, EINECS EC Number: 231-999-3 , Molecular Formula: SnF2, Molecular Weight: 156.7, HS Code ---**

Stannous fluoride is an inorganic salt and a fluoride salt. Stannous Fluoride, or Tn(II) Fluoride, is a compound commonly used in toothpastes for the prevention of gingivitis, dental infections, cavities, and to relieve dental hypersensitivity. Although similar in function and activity to Sodium Fluoride (NaF), the conventionally added ingredient in toothpastes, stannous fluoride has been shown to be more effective at stopping and reversing dental lesions. It is an FDA-approved over-the-counter product. It acts as a Lewis acid and also as a reducing agent.

Stannous Fluoride USP Grade Specifications:
SnF2 --- 156.71
Tin fluoride (SnF2).
Tin fluoride (SnF2) CAS 7783-47-3

Stannous Fluoride contains not less than 71.2 percent of stannous tin (Sn++), and not less than 22.3 percent and not more than 25.5 percent of fluoride (F), calculated on the dried basis.
Packaging and storage: Preserve in well-closed containers.

Identification:
A: To 5 mL of a solution (1 in 100) in a test tube add 2 mL of calcium chloride TS: a fine, white precipitate of calcium fluoride is formed.
B: Mix on a spot plate 2 drops of a solution (1 in 100) with 2 drops of silver nitrate TS: a brown-black precipitate is formed.
C: Add 1 drop of a solution (1 in 100) to 2 drops of mercuric chloride TS: a white, silky precipitate is formed. On further addition of the solution (1 in 100), a brown-black precipitate is formed.
pH: between 2.8 and 3.5, in a freshly prepared 0.4% solution.
Loss on drying: Dry it at 105C for 4 hours: it loses not more than 0.5% of its weight.
Water-insoluble substances: Transfer about 10 g, accurately weighed, to a 400-mL plastic beaker, add 200 mL of water, and stir with a plastic rod for 3 minutes, or until no more solid dissolves. Filter through a tared filtering crucible, and wash thoroughly, first with ammonium fluoride solution (1 in 100), then with water. [ note: Prepare and use the filtering crucible in a well-ventilated hood.] Dry the residue at 105C for 4 hours, cool, and weigh: the weight of the residue does not exceed 0.2%.
Antimony: To pass the test. --- (0.005%).
Assay for stannous ion:
0.1 N Potassium iodide-iodate: In a 1000-mL volumetric flask, dissolve 3.567 g of potassium iodate, previously dried at 110C to constant weight, in 200 mL of oxygen-free water containing 1 g of sodium hydroxide and 10 g of potassium iodide, dilute with oxygen-free water to volume, and mix. Standardize this solution by titrating a solution prepared from an accurately weighed quantity of reagent tin (Sn) and hydrochloric acid. Each mL of 0.1 N Potassium iodide-iodate is equivalent to 5.935 mg of Sn.
Procedure: Transfer about 250 mg of Stannous Fluoride, accurately weighed, to a 500-mL conical flask, and add 300 mL of hot, recently boiled 3 N hydrochloric acid. While passing a stream of an oxygen-free inert gas over the surface of the liquid, swirl the flask to dissolve the Stannous Fluoride, and cool to room temperature. Add 5 mL of potassium iodide TS, and titrate in an inert atmosphere with 0.1 N Potassium iodide-iodate, adding 3 mL of starch as the endpoint is approached. Each mL of 0.1 N Potassium iodide-iodate is equivalent to 5.935 mg of Sn++.
Assay for fluoride: [note: Store all solutions, except Buffer solution, in plastic containers.]
Buffer solution: Dissolve 57 mL of glacial acetic acid, 58 g of sodium chloride, and 4 g of (1,2-cyclohexylenedinitrilo)tetraacetic acid in 500 mL of water. Adjust with 5 N sodium hydroxide to a pH of 5.25±0.25, dilute with water to 1000 mL, and mix.
Standard preparations: Dissolve an accurately weighed quantity of USP Sodium Fluoride quantitatively in water to obtain a solution containing 420 µg per mL. Each mL of this solution (Standard preparation A) contains 190 µg of fluoride ion (10 −2 M). Transfer 25.0 mL of Standard preparation A to a 250-mL volumetric flask, dilute with water to volume, and mix. This solution (Standard preparation B) contains 19 µg of fluoride ion per mL (10 −3 M). Transfer 25.0 mL of Standard preparation B to a 250-mL volumetric flask, dilute with water to volume, and mix. This solution (Standard preparation C) contains 1.9 µg of fluoride ion per mL (0.0010 M).
Assay preparation: Transfer to a 250-mL volumetric flask about 100 mg of Stannous Fluoride, accurately weighed. Add 50 mL of water, mix vigorously for 5 minutes, dilute with water to volume, and mix. Transfer 10.0 mL of this solution to a 50-mL volumetric flask, dilute with water to volume, and mix.
Procedure: Pipet 20 mL of each Standard preparation and of the Assay preparation into separate plastic beakers each containing a plastic-coated stirring bar. Pipet 20 mL of Buffer solution into each beaker. Concomitantly measure the potentials, in mV, of the solutions from the Standard preparations and of the solution from the Assay preparation, with a pH meter capable of a minimum reproducibility of ±0.2 mV and equipped with a fluoride-specific ion-indicating electrode and a calomel reference electrode. [note: When taking measurements, immerse the electrodes in the solution, stir on a magnetic stirrer having an insulated top until equilibrium is attained (1 to 2 minutes), and record the potential. Rinse and dry the electrodes between measurements, taking care to avoid damaging the crystal of the specific-ion electrode.] Plot the logarithms of the fluoride-ion concentrations, in µg per mL, of the Standard preparations versus potential, in mV. From the measured potential of the Assay preparation and the standard reponse line, determine the concentration, C, in µg per mL, of fluoride ion in the Assay preparation. Calculate the percentage of fluoride (F) in the portion of& Stannous Fluoride taken by the formula:
