Understanding Chlorpyrifos CAS Number and Manufacturers

Chlorpyrifos is a widely used pesticide that has garnered attention due to its effectiveness in pest control and the subsequent concerns regarding its environmental and health impacts. Recognized by its Chemical Abstracts Service (CAS) number 2921-88-2, chlorpyrifos belongs to the organophosphate class of pesticides, which operate by inhibiting an enzyme essential for nerve function in insects. This article explores the significance of the CAS number, the primary manufacturers of chlorpyrifos, and the implications of its use in agriculture and public health.

The Importance of CAS Numbers

The CAS number is a unique numerical identifier assigned to every chemical substance by the Chemical Abstracts Service. It serves as a universal reference that simplifies the identification of chemicals across multiple databases, regulatory bodies, and industries. For chlorpyrifos, the CAS number 2921-88-2 ensures that researchers, manufacturers, and regulatory agencies can communicate clearly and unambiguously about this specific compound. This is crucial for tracking its usage, potential risks, and regulatory status.

Manufacturers of Chlorpyrifos

1. Dow AgroSciences (now a part of Corteva Agriscience) Dow AgroSciences was one of the original developers of chlorpyrifos in the 1960s. It has been a leader in the production of various pesticides, including chlorpyrifos, which has been a staple in agricultural pest control for decades.

2. Sipcam Agro This company is involved in the formulation and distribution of chlorpyrifos-based products in various countries. They focus on providing sustainable agricultural solutions while adhering to regulatory guidelines regarding pesticide use.

3. Cheminova (now part of FMC Corporation) Cheminova was another significant producer of chlorpyrifos, supplying the agricultural industry with effective pest control solutions. FMC Corporation continues to produce and market chlorpyrifos formulations through its acquisition.

4. Adama Agricultural Solutions This company actively produces chlorpyrifos under various brand names, catering to different markets globally. They emphasize innovation in agriculture while addressing safety and environmental concerns.

5. UPL Ltd. UPL manufactures a range of agrochemicals, including chlorpyrifos. They focus on providing comprehensive crop protection solutions and have a significant presence in international markets.

Environmental and Health Concerns

While chlorpyrifos has been a popular choice for controlling pests in crops such as corn, soybeans, and fruits, it has faced substantial scrutiny regarding its safety. Research has linked exposure to chlorpyrifos with negative health effects, particularly in children. The pesticide can disrupt neurodevelopment and has been associated with developmental disorders. These concerns have led to increased regulation and, in some regions, outright bans on its use.

The U.S. Environmental Protection Agency (EPA) has been reviewing the safety and efficacy of chlorpyrifos, leading to significant regulatory changes. Many states and countries have either restricted or prohibited the use of chlorpyrifos due to these health concerns. As farmers seek alternatives, the pesticide industry is innovating to develop safer and more sustainable pest control options.

Conclusion

Chlorpyrifos, represented by its CAS number 2921-88-2, has played a pivotal role in agricultural pest management for decades. Although it is manufactured by several reputable companies, growing concerns over its health and environmental implications have prompted regulatory scrutiny and calls for safer alternatives. As the agricultural landscape evolves, it is imperative for manufacturers, farmers, and policymakers to work together to ensure effective pest control while safeguarding public health and the environment. Transitioning to safer practices and products will not only provide a more sustainable future for agriculture but also protect the health of all individuals impacted by pesticide use.
