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.
Tributyltin chloride is an organotin compound with the formula (C 4 H 9) 3 SnCl. It is a colorless liquid that is soluble in organic solvents. Preparation and reactions
3 R 4 Sn + SnCl 4 → 4 R 3 SnCl R 4 Sn + SnCl 4 → 2 R 2 SnCl 2 R 4 Sn + 3 SnCl 4 → 4 RSnCl 3. A related method involves redistribution of tin halides with organoaluminium compounds. [2]: 45–47 In principle, alkyltin halides can be formed from direct insertion of the metal into the carbon-halogen bond.

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.
Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds.It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods.
Tin(II) hydroxide, Sn(OH) 2, also known as stannous hydroxide, is an inorganic compound tin(II). The only related material for which definitive information is available is the oxy hydroxide Sn 6 O 4 (OH) 4, but other related materials are claimed. They are all white solids that are insoluble in water.
SnO 2 + 2 KSCN → SnS + K 2 S + 2CO + N 2. SnS also forms when aqueous solutions of tin(II) salts are treated with hydrogen sulfide. [5] This conversion is a step in qualitative inorganic analysis. At cryogenic temperatures, stannous chloride dissolves in liquid hydrogen sulfide. It then decomposes to the sulfide, but only slowly. [6]
