3,5-Dichloroaniline (CAS 626-43-7) is a fundamental organic compound with specific chemical properties that dictate its utility in various industrial applications. As a fine chemical intermediate, understanding its molecular structure, physical characteristics, and synthesis routes is crucial for chemists and formulators. This article explores these key aspects, providing valuable insights for R&D scientists and production managers.

Physically, 3,5-Dichloroaniline typically presents as a white to light yellow crystalline powder. Its melting point is in the range of 49-53°C, and its boiling point is approximately 260°C at 741 mmHg. The solubility profile is notable: it exhibits moderate solubility in water (0.6 g/L at 26°C) but is more soluble in organic solvents like ethanol and ether. These properties are critical for its handling, purification, and reaction kinetics in various synthesis processes.

Chemically, it is an aniline derivative with two chlorine atoms substituted at the meta positions of the benzene ring. This specific arrangement influences its reactivity. The presence of the amino group and the electronegative chlorine atoms contributes to its role as an intermediate in complex organic reactions. Its stability is generally good under normal handling, though it can undergo color changes upon exposure to light and air, necessitating appropriate storage conditions, often recommended at 0-6°C.

The synthesis of 3,5-Dichloroaniline typically involves multi-step chemical transformations. A common pathway begins with the chlorination of an appropriate precursor, followed by reduction steps to form the amine group. For example, hydrogenation of 3,5-dichloronitrobenzene is a direct route to produce 3,5-Dichloroaniline. This preparation method ensures a higher degree of control over the final product's purity, which is essential for its use in pharmaceutical and agrochemical applications. Manufacturers often employ optimized industrial processes to achieve high yields and purity.
