Ensuring the safe and responsible use of chemical compounds is paramount across all industries. 2-Phenylphenol (CAS 90-43-7), while highly versatile, comes with specific safety and regulatory considerations that users must be aware of. Understanding the 'chemical properties of CAS 90-43-7' in relation to safety is the first step.

2-Phenylphenol is classified with hazard symbols indicating it is an irritant (Xi) and dangerous for the environment (N). This means it can cause skin and eye irritation and may be harmful to aquatic life. Appropriate personal protective equipment (PPE), such as gloves, eye protection, and respiratory protection if handling powders, is essential when working with this compound. The 'O-phenylphenol disinfectant uses' must be balanced with these safety precautions.

Regulatory bodies often establish guidelines for the use of chemicals like 2-phenylphenol, particularly in applications involving food contact or agricultural products. For instance, its use as a food additive has been restricted in some regions, emphasizing the need to adhere to the latest regulations and guidelines. The '2-phenylphenol fungicide' application in agriculture is subject to strict approval processes and residue limits in many countries.

When sourcing 2-phenylphenol, it is imperative to obtain comprehensive Safety Data Sheets (SDS) from the manufacturer. These documents provide detailed information on hazard identification, handling and storage, exposure controls, toxicological information, and disposal considerations. Knowledge of the '2-phenylphenol synthesis methods' is less critical for end-users than understanding the safety data associated with the final product.

Environmental considerations are also significant. Due to its potential to be harmful to aquatic organisms, release into the environment should be minimized. Proper waste disposal practices, in accordance with local and national regulations, are crucial. The 'applications of biphenyl-2-ol' should always be assessed for their environmental impact.

In conclusion, while 2-phenylphenol offers significant benefits across various sectors, its handling and application must be guided by a thorough understanding of its safety profile and regulatory requirements. Adhering to these guidelines ensures the protection of human health and the environment, promoting the responsible use of this important chemical.
