For professionals in the chemical, pharmaceutical, and agricultural industries, a thorough understanding of key intermediates like 4-Chloroaniline (CAS: 106-47-8) is fundamental. This aromatic amine serves as a versatile building block, enabling the synthesis of a wide array of valuable products. Beyond its common uses, grasping its physical and chemical properties, along with proper handling and safety protocols, is crucial for efficient and secure industrial operations.

Chemically, 4-Chloroaniline is characterized by its chlorine atom and amine group attached to a benzene ring, imparting specific reactivity. Its typical appearance is as colorless to light yellow crystals, with a melting point around 72.5 °C and a boiling point of 232 °C. The assay is typically specified as ≥99.0%, highlighting the importance of purity for its intended applications. These properties make it suitable as an intermediate in reactions requiring an aniline derivative with specific electrophilic or nucleophilic characteristics.

The primary industrial applications for 4-Chloroaniline are diverse. It is a cornerstone intermediate for the synthesis of numerous azo dyes and pigments, providing the chromophoric backbone for many vibrant colors. In the pharmaceutical sector, it's a precursor for synthesizing important drug molecules, contributing to advancements in medicine. Furthermore, its role extends to the agrochemical industry, where it's used in the production of pesticides, aiding in crop protection and yield enhancement. Its utility also finds a niche in the production of color films.

Given its chemical nature, safe handling of 4-Chloroaniline is imperative. Safety Data Sheets (SDS) typically classify it as a toxic substance, potentially harmful if inhaled, ingested, or absorbed through the skin. It can also be an irritant. Therefore, industrial professionals must adhere to strict safety guidelines, including wearing appropriate personal protective equipment (PPE) such as gloves, eye protection, and respiratory protection, especially when handling the powder form or working in areas where airborne concentrations might occur. Proper ventilation in work areas is also critical.

When sourcing 4-Chloroaniline, B2B buyers should prioritize manufacturers who provide comprehensive safety information and maintain high standards of quality control. Understanding these properties and applications allows industrial professionals to leverage 4-Chloroaniline effectively and safely, ensuring both product quality and operational integrity.
