2-Amino-4,6-dimethylbenzoic acid(CAS: 90321-33-8)

2-Amino-4,6-dimethylbenzoic acid (CAS: 90321-33-8) is a crystalline solid with a molecular weight of approximately 208.22 g/mol. It is slightly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can undergo hydrolysis in strong bases. It has a pKa of around 4.5 and is a weak acid.

2-Amino-4,6-dimethylbenzoic acid is commonly synthesized via the condensation of o-chloroaniline with dimethylformamide in the presence of a catalyst such as p-toluenesulfonic acid. The reaction is typically carried out at elevated temperatures, and the product is obtained with good yield and selectivity.

2-Amino-4,6-dimethylbenzoic acid is primarily used in the pharmaceutical industry for the synthesis of certain drugs. It is also employed in the polymer industry as a monomer for the production of advanced materials and in the sensor industry for the development of chemical sensors. Additionally, it finds applications in the semiconductor industry as a dopant.

When handling 2-Amino-4,6-dimethylbenzoic acid (CAS: 90321-33-8), it is essential to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be contained and disposed of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and safety instructions.
