2-Phenylphenol, identified by its CAS number 90-43-7, is a compound whose chemical structure dictates a range of useful properties and reactivities. Understanding these characteristics is fundamental to its widespread application in industries ranging from agriculture to chemical manufacturing. Delving into the 'chemical properties of CAS 90-43-7' provides a foundational understanding of its utility.

Physically, 2-phenylphenol is typically described as a white to off-white crystalline solid, often in the form of flakes. Its melting point generally falls in the range of 57-59°C, and it has a boiling point of around 282°C. This solid state at room temperature and moderate volatility contribute to its handling and application characteristics. The 'applications of biphenyl-2-ol' are diverse, stemming from these physical traits.

Chemically, 2-phenylphenol exhibits properties characteristic of phenols, including a weakly acidic nature. It is soluble in various organic solvents such as ethanol, acetone, and ether, but has limited solubility in water. This solubility profile is important for formulating solutions for specific applications, whether for agricultural treatment or industrial processes. The compound can react with strong bases, undergoing neutralization reactions.

Its reactivity also extends to its use as a chemical intermediate. The hydroxyl group on the phenyl ring allows for further chemical modifications, enabling its incorporation into larger molecular structures. This makes it a valuable precursor for synthesizing polymers, stabilizers, and flame retardants. Manufacturers often rely on precise '2-phenylphenol synthesis methods' to achieve the desired purity and reactivity for these downstream applications.

While generally stable under normal conditions, 2-phenylphenol can react with strong oxidizing agents. Its properties also necessitate careful handling due to its irritant and environmental hazard classifications. Understanding these aspects, including its 'O-phenylphenol disinfectant uses' and associated safety protocols, is crucial for responsible use.

In summary, the scientific understanding of 2-phenylphenol's physical and chemical properties, including its solubility, melting point, and reactivity, underpins its diverse applications. Whether utilized for its fungicidal action, disinfectant properties, or as a key intermediate in synthesis, a thorough grasp of its science is essential for maximizing its benefits.
