    Application Areas

    Pharmaceutical intermediates: used for synthesizing steroid hormone drugs
    Organic synthesis: as an intermediate for synthesizing other organic compounds

    Storage conditions

    Environmental requirements
    It should be stored in a cool, well ventilated dedicated warehouse, away from sources of fire, heat, and direct sunlight.
    The storage container should be strictly sealed to avoid mixing with oxidants, strong acids and bases.
    It is recommended to use fire-resistant warehouses or explosion-proof storage cabinets, and equip them with secondary leak proof containers.
    Temperature control and zoning
    Maintain stable temperature in the storage area to avoid volatilization or decomposition caused by high temperatures.
    Store according to the classification standards for hazardous chemicals, avoiding adjacent substances with conflicting properties

    Safety precautions

    Operation protection
    Operators are required to wear dust masks, anti-seepage gloves, and goggles, as well as anti-static work clothes.
    The operating area should be equipped with a local exhaust system to prevent the accumulation of dust or steam.
    Fire Protection and Monitoring
    Explosion proof fire extinguishers (such as dry powder or carbon dioxide fire extinguishers) need to be installed in the warehouse.
    Regularly check the integrity of storage containers and monitor the concentration of combustible gases in the environment

    FAQ - Technical & Supply Chain

    • Q:

      Do Dienolone and 17β-Hydroxyestra-4,9-dien-3-one refer to the same substance?

      A: Yes. These names describe the same molecular structure and correspond to a single CAS registration, indicating identical substance identity.
    • Q:

      Is Dienolone typically used as an industrial intermediate rather than a finished pharmaceutical product?

      A: It is commonly intended for use as a chemical intermediate in steroid synthesis and related industrial chemical processes, not as a finished dosage form.
