Usage

General Description

Metastannic acid, also known as stannic acid, is a chemical compound with the formula H2SnO3. It is a white, amorphous powder that is insoluble in water and most organic solvents. Metastannic acid is used as a catalyst in organic synthesis, particularly in the production of polyurethanes and esters. It also has applications in the manufacturing of ceramic materials, electroplating, and as a stabilizer in the production of plastics and rubber. Metastannic acid is a strong Lewis acid, meaning it is capable of accepting electron pairs from other molecules, making it a versatile and important chemical in various industrial processes.
