Additionally, SnCl 2 is used to selectively reduce aromatic nitro groups to anilines. [11] Aromatic nitro group reduction using SnCl 2. SnCl 2 also reduces quinones to hydroquinones. Stannous chloride is also added as a food additive with E number E512 to some canned and bottled foods, where it serves as a color-retention agent and antioxidant.

Tin(IV) chloride, also known as tin tetrachloride or stannic chloride, is an inorganic compound of tin and chlorine with the formula SnCl 4. It is a colorless hygroscopic liquid , which fumes on contact with air.
The compound is prepared by a redistribution reaction by combining stannic chloride and tetrabutyltin: 3 (C 4 H 9) 4 Sn + SnCl 4 → 4 (C 4 H 9) 3 SnCl. Tributyltin chloride hydrolyzes to the oxide [(C 4 H 9) 3 Sn] 2 O Tributyltin chloride is used as a precursor to other organotin compounds [1] and reagents, such as tributyltin hydride.
A chloride ion is a structural component of some proteins; for example, it is present in the amylase enzyme. For these roles, chloride is one of the essential dietary mineral (listed by its element name chlorine). Serum chloride levels are mainly regulated by the kidneys through a variety of transporters that are present along the nephron. [19]
Tin(IV) chloride was added to dinitrogen pentoxide at -78 °C, which produced tin(IV) nitrate and nitryl chloride: [4] SnCl 4 + 4 N 2 O 5 → Sn(NO 3) 4 + 4 NO 2 Cl. Attempts to prepare this compound by reacting tin(II) oxide and nitric acid resulted in a formation of tin(II) nitrate hydroxide. [5]
Tin(II) oxalate is an inorganic compound, a salt of tin and oxalic acid with the chemical formula SnC 2 O 4. [2] The compound looks like colorless crystals, does not dissolve in water, and forms crystalline hydrates.
Trimethyltin chloride can be prepared by the redistribution reaction of tetramethyltin with tin tetrachloride. [3]SnCl 4 + 3 Sn(CH 3) 4 → 4 (CH 3) 3 SnCl. This redistribution reaction is typically performed with no solvent because high temperatures are required and purification is simplified.
