4-Chloro-3-methylaniline(CAS: 7149-75-9)

4-Chloro-3-methylaniline is a white crystalline solid with a molecular weight of approximately 169.59 g/mol. It is slightly soluble in water and soluble in organic solvents like ethanol and acetone. It is moderately reactive, particularly towards nucleophiles and electrophiles, and can undergo substitution reactions. The compound is often used in organic synthesis due to its reactivity.

4-Chloro-3-methylaniline is commonly synthesized via the reaction of 3-methylaniline with chlorine gas or chloromethylbenzene. The reaction typically proceeds under mild conditions, often in the presence of a phase transfer catalyst. The yield is around 70-80%, with good selectivity towards the desired product.

4-Chloro-3-methylaniline is primarily used in the pharmaceutical industry for the synthesis of drugs, particularly those that require chlorine substituents. It is also utilized in the production of certain dyes and pigments, as well as in the manufacturing of organic semiconductors and sensors.

When handling 4-Chloro-3-methylaniline, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up immediately using appropriate absorbents, and the area should be monitored for any contamination. Always refer to the Safety Data Sheet (SDS) for detailed safety information.
