Decachloroketone, also known as DC-ketone, is a potent chemical compound featuring a ketone group bonded to ten chlorine atoms. It is distinguished by its exceptional stability and flame resistance, which render it a highly effective fire retardant and extinguishing agent. Despite its utility in fire safety, its high toxicity and potential health and environmental hazards have led to regulatory measures restricting its production and use in many countries.

    Hazards Summary:

    Mirex and chlordecone are two separate, but chemically similar, manufactured insecticides that do not occur naturally in the environment. Mirex is a white crystalline solid, and chlordecone is a tan-white crystalline solid. Both chemicals are odorless. Mirex and chlordecone have not been manufactured or used in the United States since 1978. Mirex was used to control fire ants, and as a flame retardant in plastics, rubber, paint, paper, and electrical goods from 1959 to 1972. Chlordecone was used as an insecticide on tobacco, ornamental shrubs, bananas, and citrus trees, and in ant and roach traps. Mirex was sold as a flame retardant under the trade name Dechlorane, and chlordecone was also known as Kepone. Use of trade names is for identification only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry, the Public Health Service, or the U.S. Department of Health and Human Services.

    Uses

    Used in Fire Safety Industry:
    Decachloroketone is used as a fire retardant for its ability to prevent the spread of flames and reduce the risk of fire in various materials. Its high stability and resistance to combustion make it a reliable component in fire safety applications.
    Used in Fire Extinguishing Equipment:
    In fire extinguishers, Decachloroketone serves as an extinguishing agent, effectively suppressing fires through its chemical properties that inhibit combustion. Its inclusion in extinguishing systems enhances their performance in emergency situations.
    However, due to the recognized health and environmental risks associated with Decachloroketone, there has been a significant reduction in its usage and production, leading to a search for safer alternatives in fire safety technologies.

    Check Digit Verification of cas no

    The CAS Registry Mumber 143-50-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
    Calculate Digit Verification of CAS Registry Number 143-50:
    (5*1)+(4*4)+(3*3)+(2*5)+(1*0)=40
    40 % 10 = 0
    So 143-50-0 is a valid CAS Registry Number.
