Tin Fluoride or Stannous Fluoride CAS Number 7783-47-3

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.

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: To pass the test. 71.2 percent of stannous tin (Sn++) minimum.
Assay for fluoride: To pass the test. 25.5 percent of fluoride (F) minimum.
