TPAH is one of the most widely used structure-directing agents or templates in the hydrothermal synthesis of various zeolites (e.g., ZSM-5, Beta, Silicalite-1) and other porous materials. It plays a crucial role in directing the formation of specific framework structures and controlling pore dimensions.
Strong Organic Base and Catalyst:
As a strong, non-nucleophilic organic base, TPAH is employed as a catalyst or reagent in numerous organic reactions, including condensation reactions, esterifications, polymerizations, and dehydrohalogenations, especially where inorganic bases might interfere or cause side reactions.
Electrolyte in Electrochemical Applications:
TPAH is utilized as a supporting electrolyte in various electrochemical studies and processes, particularly in non-aqueous solvents, due to its high ionic conductivity and stability over a wide potential range.
Precursor for Specialty Chemicals:
It serves as a key precursor in the synthesis of other specialized quaternary ammonium compounds and derivatives, which find applications as phase-transfer catalysts, surfactants, and antimicrobial agents.
High-Purity Material Production:
In the electronics industry and other high-tech sectors, TPAH is used in the production of high-purity materials, including certain metal oxides and thin films, where precise control over pH and cation presence is required.
Etchant in Semiconductor Manufacturing:
In some semiconductor fabrication processes, TPAH solutions can be used as a selective etching agent for silicon and other materials.

We utilize various UN (United Nations) certified packaging containers based on the chemical nature, hazard class, and transportation requirements of our products. Common packaging types include, but are not limited to: Steel Drums: Suitable for a wide range of liquid and solid products, especially flammable liquids. Plastic Drums/Jerricans: Primarily used for corrosive liquids like acids and bases, or substances incompatible with metal. Composite Drums: Combine the corrosion resistance of a plastic inner liner with the strength of a steel or fiber outer shell. IBCs (Intermediate Bulk Containers): Often referred to as "Tote Bins" or "Cubic Tanks," these are used for larger volumes of liquid or solid dangerous goods, offering efficient storage and transport solutions. Lined Bags or Fibre Drums: Primarily used for powdered or granular solids. Glass Bottles: Typically used as inner packaging for small quantities of high-purity or specialized chemicals, requiring additional absorbent material and sturdy outer packaging (e.g., wooden crates, fiberboard boxes). Steel Cylinders: Specifically designed and constructed as pressure vessels for the storage and transport of compressed, liquefied, or dissolved gases. Available in various capacities and pressure ratings, they are built to withstand high internal pressures and ensure the safe containment of gaseous substances.

Upon receiving your shipment, please carefully verify the integrity of the packaging and the label information.
| Proper storage is crucial for maintaining product quality and ensuring operational safety. The following are general storage principles: Dedicated Areas: Dangerous chemicals should be stored in designated warehouses or areas that meet safety standards, away from residential zones and densely populated areas. Segregated Storage: Strictly classify and segregate products according to their hazard class to prevent incompatible substances from being stored together and causing dangerous reactions (e.g., acids and bases separated, flammables away from oxidizers). Good Ventilation: Storage areas should maintain good natural or forced ventilation to prevent the accumulation of hazardous gases or vapors. Temperature & Humidity Control: Control the temperature and humidity of the storage environment according to the recommendations in the SDS. Avoid direct sunlight and extreme temperatures. Fire and Explosion Prevention: Storage areas for flammable and explosive products should be equipped with adequate fire-fighting equipment, prohibit open flames, and ensure electrical equipment meets explosion-proof standards. Clear Labeling: All storage containers and areas should have clear, conspicuous hazard labels and warning signs. Spill Response: Storage areas should be equipped with appropriate spill response equipment and materials, and personnel should be familiar with emergency procedures. Regular Inspections: Periodically inspect the integrity of storage containers to ensure no leaks or damage, and verify label information. Away from Food and Drinking Water: Avoid cross-contamination.
