With the CAS registry number 7783-47-3, the product name and IUPAC name of this chemical are the same which is called Tin(II) fluoride. Known by the common name stannous fluoride, it is a chemical compound with the formula SnF₂. It belongs to the product category of Inorganics. Its EINECS registry number is 231-999-3. 

Physical properties of Tin(II) fluoride: (1)H-Bond Donor: 0; (2)H-Bond Acceptor: 2; (3)Rotatable Bond Count: 0; (4)Exact Mass: 157.899003; (5)MonoIsotopic Mass: 157.899003; (6)Topological Polar Surface Area: 0; (7)Heavy Atom Count: 3; (8)Formal Charge: 0; (9)Complexity: 2.8; (10)Isotope Atom Count: 0; (11)Defined Atom StereoCenter Count: 0; (12)Undefined Atom StereoCenter Count: 0; (13)Defined Bond StereoCenter Count: 0; (14)Undefined Bond StereoCenter Count: 0; (15)Covalently-Bonded Unit Count: 1.

Preparation of Tin(II) fluoride: this chemical can be prepared by evaporating a solution of SnO in 40% HF.

Uses of Tin(II) fluoride: This chemical is used as an ingredient in toothpastes that are typically more expensive than those that use sodium fluoride. Used in combination with calcium minerals, sodium fluoride is ineffective while stannous fluoride remains effective in strengthening tooth enamel. Stannous fluoride has also been shown to be more effective than sodium fluoride in controlling gingivitis. Stannous fluoride was used, under the trade name "Fluoristan," in the original formulation of the toothpaste Crest, though it was later replaced with sodium monofluorophosphate, or "Fluoristat."

When you are using this chemical, please be cautious about it as the following:
This chemical may cause damage to health and may destroy living tissue on contact. It is harmful if swallowed. In addition, it is irritating to skin. There will be a risk of serious damage to eyes. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. Whenever you will contact it, please wear eye/face protection.
