    Dipropyl Ether CAS 111-43-3

    Dipropyl ether is a symmetrical aliphatic ether composed of two n‑propyl groups linked by an oxygen atom. This defined molecular structure places it within the class of low‑molecular‑weight aliphatic ethers supplied through professional chemical supply chains. Dipropyl Ether (CAS 111-43-3) is handled as a discrete chemical substance in regulated industrial and research environments, where accurate material identification, documentation, and compliance are essential.
    The material is supplied with standardized specifications and complete technical documentation, including MSDS, TDS, and COA, supporting traceability and regulatory conformity.

    Application Areas

    Organic synthetic solvents: Due to their good solubility (soluble in most organic solvents such as ethanol and ether), they are commonly used in laboratory and industrial chemical reactions.
    Extraction agent: used as a non-polar solvent in the separation and purification process.

    Storage conditions

    Environmental requirements: Store in a cool, well ventilated warehouse, away from sources of fire and heat, and avoid direct sunlight.
    Container selection: Use stainless steel or glass containers with good sealing to avoid contact with oxidants.
    Temperature control: It is recommended to store at a temperature below 25 ℃ to prevent container rupture caused by increased vapor pressure

    Safety precautions

    Fire and explosion prevention: Low flash point (21 ℃), explosion-proof electrical equipment and ventilation system are required. Avoid contact with open flames, sparks, or high-temperature surfaces.
    Personal protection: Wear chemical goggles, gas masks, and solvent resistant gloves during operation. The workplace should be equipped with eye wash stations and emergency shower equipment.
    Leakage treatment: Use adsorbent materials (such as sand) to collect the leaked material, and it is strictly prohibited to rinse with water
