    As an accredited Tetrabutylphosphonium Hydroxide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.

    Packing & Storage
    Packing Tetrabutylphosphonium Hydroxide is supplied in a 500 mL amber glass bottle with a secure, chemical-resistant screw cap and safety label.
    Shipping Tetrabutylphosphonium Hydroxide should be shipped in tightly sealed, chemical-resistant containers to prevent leaks. It must be protected from moisture and incompatible materials. The package should be clearly labeled, and transport should comply with all relevant regulations for corrosive substances. Use secondary containment and appropriate hazard communication during shipping.
    Storage Tetrabutylphosphonium Hydroxide should be stored in a tightly closed, corrosion-resistant container, away from moisture and carbon dioxide. Keep it in a cool, dry, well-ventilated area, away from incompatible materials such as acids and oxidizers. Store at room temperature or as recommended by the manufacturer, and ensure proper labeling and secondary containment to prevent leaks or spills.
