1. PVC Processing Stabilizer Synthesis:
It is a core intermediate in the synthesis of high-efficiency PVC heat stabilizers such as thiol methyltin. These stabilizers are characterized by high efficiency, low toxicity, and high transparency, effectively inhibiting thermal decomposition and discoloration during PVC processing. They are suitable for the production of PVC products with high stability and purity requirements, such as transparent PVC films and PVC medical devices.

2. High-End Glass Coating Manufacturing:
It can be used in the preparation of coatings for Low-E (low-emissivity) glass and TCO (transparent conductive oxide) photovoltaic glass. Incorporating it into the coating system improves the optical and thermal properties of the glass. For example, Low-E glass can reduce heat transfer between the interior and exterior, and TCO photovoltaic glass can optimize the light transmission and conductivity during the photoelectric conversion process, making it suitable for energy-efficient building windows and photovoltaic modules. It can also be used in the production of hot-end coatings for glass bottles, ensuring stable surface properties of the glass bottles.

3. Chemical Synthesis Catalysis:
It acts as a highly efficient catalyst in esterification reactions, accelerating the reaction between carboxylic acids and alcohols to form esters, shortening production cycles and reducing energy consumption. This application is common in the synthesis of ester compounds in fine chemicals, such as the preparation of ester solvents for coatings and ester components in fragrances and flavors, helping to ensure product yield and purity. In addition, its high purity characteristics allow it to be used as an intermediate in some pharmaceutical synthesis reactions, meeting the needs of some fine chemical synthesis in the pharmaceutical field.

4. Metal Corrosion Protection:
It can be used as a corrosion inhibitor for magnesium and magnesium alloys, usually in an aqueous solution. Magnesium alloys are prone to corrosion; applying it to the protection of magnesium alloy components used in aerospace and automotive industries can slow down the corrosion rate of components in service environments, extending the service life of magnesium alloy components and ensuring the operational reliability of related equipment.

5. Functional Materials Preparation:
It is used in the preparation of electroluminescent materials. Its unique chemical structure can help improve the luminous efficiency and stability of electroluminescent materials.

6. Other auxiliary fields in the chemical industry:
Due to its excellent chemical activity and high purity, it can also be used as a basic intermediate in organic synthesis, for the synthesis of various other organotin compounds. This further expands its applications to related derivative fields such as textile auxiliaries and chemical additives, providing raw material support for the performance optimization of different chemical products.
