2,4-Dimethyl-5-nitroaniline(CAS: 2124-47-2)

2,4-Dimethyl-5-nitroaniline (CAS: 2124-47-2) is a crystalline solid with a molecular weight of approximately 194.13 g/mol. It has a pKa of about 5.3 and is slightly soluble in water (0.1 g/L at 25°C). This compound is relatively stable but can react under acidic or basic conditions. It is used in various applications due to its chemical reactivity and stability.

2,4-Dimethyl-5-nitroaniline (CAS: 2124-47-2) is commonly synthesized through the nitration of 2,4-dimethylaniline using a nitric acid and sulfuric acid mixture under controlled conditions. The reaction is typically carried out at room temperature, and the product is isolated by recrystallization. This method provides a high yield and good purity.

2,4-Dimethyl-5-nitroaniline (CAS: 2124-47-2) is used in the pharmaceutical industry for the synthesis of certain drugs, particularly those requiring aromatic nitro groups. It is also used in the manufacturing of dyes and pigments, as well as in the production of some agricultural chemicals and explosives.

When handling 2,4-Dimethyl-5-nitroaniline (CAS: 2124-47-2), proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. Work should be conducted in a well-ventilated area or under a fume hood. Spills should be contained and cleaned up using appropriate methods, and the material safety data sheet (MSDS) should be consulted for specific instructions. Storage should be in a cool, dry place away from incompatible materials.
