Prop-1-en-2-ylbenzene; styrene(CAS: 9011-11-4)

Styrene (CAS: 9011-11-4) is regulated under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) as a flammable liquid and skin and eye irritant. In the European Union, it is regulated under REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) with specific restrictions. FDA and EPA have set permissible exposure limits and environmental discharge standards to ensure worker safety and environmental protection.

There are several alternatives to styrene (CAS: 9011-11-4) in synthesis, including phenylacetylene and vinylbenzene. These alternatives can offer similar chemical reactivity and functional group compatibility, providing flexibility in synthetic approaches. However, their use may require different handling procedures and safety measures.

The market for styrene (CAS: 9011-11-4) is driven by its widespread use in the production of polystyrene plastics, rubber, and resins. Research trends focus on developing more sustainable and biodegradable alternatives, as well as exploring its potential in new applications such as advanced materials and electronics. The increasing demand in emerging markets and ongoing technological advancements are key drivers in this field.

Waste containing styrene (CAS: 9011-11-4) should be collected in designated containers and stored in a well-ventilated area. Proper incineration or professional waste disposal services should be utilized. Environmental protection measures include minimizing spillage and ensuring that waste is handled in accordance with local regulations to prevent contamination of water and soil.
