Understanding CAS No. 2682-20-4 A Comprehensive Overview

CAS No. 2682-20-4 refers to a specific chemical compound known as 2-(2H-benzotriazol-2-yl)-4,6-di-tert-butylphenol. This compound belongs to a class of chemicals known as UV stabilizers and has a variety of applications across different industries, including plastics, coatings, and personal care products. In this article, we will explore the structure, properties, applications, and safety concerns related to CAS No. 2682-20-4.

Chemical Structure and Properties

The molecular formula of 2-(2H-benzotriazol-2-yl)-4,6-di-tert-butylphenol can be denoted as C16H18N2O. Its structure comprises a phenolic group decorated with two tert-butyl groups, positioned at the 4 and 6 positions relative to the hydroxyl functional group. Additionally, it features a benzotriazole moiety that serves to absorb ultraviolet (UV) light, thus rendering the compound effective as a UV stabilizer. This combination allows the compound to provide enhanced stability and resistance to photodegradation, which is especially valuable in applications where materials are exposed to sunlight.

The primary application of CAS No. 2682-20-4 is in the stabilization of plastics and polymers. When added to polymer formulations, this compound helps prevent the degradation of materials caused by UV radiation. This is crucial in outdoor applications, where plastics are subjected to prolonged sunlight exposure, leading to color fading, loss of mechanical properties, and eventual material failure. By incorporating this UV stabilizer, manufacturers can extend the lifespan of products such as outdoor furniture, automotive components, and construction materials.

In addition to its role in plastics, the compound is also used in coatings, adhesives, and sealants. These products benefit from improved durability and performance when exposed to harsh environmental conditions. Furthermore, CAS No. 2682-20-4 finds applications in personal care items, such as sunscreens and lotions, where it helps safeguard active ingredients from photodegradation, ensuring efficacy and safety for consumers.

Environmental and Safety Considerations

As with many chemicals, the handling and use of CAS No. 2682-20-4 come with safety considerations. It is essential for manufacturers and users to adhere to established safety protocols to minimize exposure and environmental impact. Studies relating to its ecotoxicity and biodegradability are ongoing, which is critical for assessing the compound’s long-term environmental effects.

Regulatory agencies are increasingly scrutinizing chemical compounds for their environmental impact and potential human health risks. The European Union's REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation plays a significant role in managing these concerns. As a registered substance, manufacturers must provide data demonstrating that CAS No. 2682-20-4 is used safely and responsibly, particularly with regard to exposure limits and environmental release.

Conclusion

CAS No. 2682-20-4 serves a critical role as a UV stabilizer in various industries, ensuring the longevity and performance of materials exposed to sunlight. Its unique chemical structure allows it to absorb UV radiation effectively, making it an invaluable addition to plastics, coatings, and personal care products. However, as the demand for sustainable and environmentally friendly practices increases, it will be essential for industry stakeholders to monitor and manage the use of this compound responsibly.

Understanding the intricate balance between performance and safety will help pave the way for innovations that not only meet consumer needs but also contribute to environmental preservation. Future research will likely continue to shed light on the environmental behavior and health effects of CAS No. 2682-20-4, ensuring that its applications align with global sustainability goals. In a world increasingly focused on eco-friendly practices, the responsible management of chemical substances will be paramount in driving future advancements.
