2,5-Dichlorophenol (CAS 583-78-8) stands as a significant compound within the chemical industry, particularly recognized for its critical function as an intermediate in the synthesis of pesticides, most notably herbicides. This article aims to explore the detailed chemical and physical properties of 2,5-Dichlorophenol, shedding light on why these attributes make it an invaluable component in the pesticide intermediate manufacturing sector.

The compound's physical appearance is typically described as a white powder, indicating a solid state at standard room temperatures. Its purity, often exceeding 99.0%, is a crucial specification for its industrial applications, ensuring that the subsequent chemical reactions proceed with high efficiency and yield. The molecular formula, C6H4Cl2O, and a molecular weight of 163.001 g/mol, define its basic chemical identity. These characteristics are foundational for understanding its behavior in various synthesis pathways.

Further examination of its physical properties reveals a melting point range of 54-57 °C, suggesting a relatively low melting point for an organic solid. Its boiling point is recorded at approximately 214.6 °C at 760 mmHg, indicating its thermal stability under atmospheric pressure. The flash point, around 100.0 °C, provides an indication of its flammability. Importantly, its water solubility is noted as 3 g/L at 20 °C, a figure that influences its use in aqueous-based processes and its environmental fate. The LogP value of 2.88 suggests moderate lipophilicity, affecting its partitioning behavior in different media.

The primary application that underscores the importance of 2,5-Dichlorophenol is its role as a precursor in the synthesis of Dicamba. Dicamba is a highly effective selective herbicide used globally to manage broadleaf weeds that compete with crops, thus playing a vital role in modern agriculture and food production. The precise structure of 2,5-Dichlorophenol, with its strategically placed chlorine atoms on the phenol ring, is essential for imparting the desired herbicidal activity to the final Dicamba molecule. This makes it a key compound for businesses involved in herbicide synthesis and the broader field of agrochemicals.

Storage and handling are also critical considerations for maintaining the integrity of 2,5-Dichlorophenol. It is generally recommended to store it in a cool, dry, and well-ventilated place, with containers kept tightly closed to prevent degradation or contamination. Proper packaging, typically in 25kg drums, is also standard practice to ensure safe transport and storage, catering to the needs of industrial clients.

In essence, 2,5-Dichlorophenol serves as a fundamental component in the chemical value chain that supports agricultural productivity. Its well-defined chemical properties, combined with its indispensable role in creating essential crop protection agents, solidify its position as a significant intermediate in the global chemical market.
