5,6-Dichloropicolinic acid(CAS: 88912-24-7)

5,6-Dichloropicolinic acid (CAS: 88912-24-7) is a white crystalline solid with a molecular weight of approximately 225.03 g/mol. It is sparingly soluble in water and has limited solubility in organic solvents. This compound is known for its acidic nature, with a pKa of around 1.4. It is also relatively stable, but can react with bases to form salts.

5,6-Dichloropicolinic acid can be synthesized via the chlorination of picolinic acid under appropriate conditions. A common method involves treating picolinic acid with chlorine gas in the presence of a suitable catalyst, such as ferric chloride, to selectively introduce the dichloro substituents. The yield and selectivity of the reaction can be significantly influenced by the reaction conditions and the choice of catalyst.

5,6-Dichloropicolinic acid is used in various industries. It is a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antibacterial and anticancer drugs. It also finds applications in the production of polymers and as a component in sensors and semiconductors.

When handling 5,6-Dichloropicolinic acid (CAS: 88912-24-7), it is important to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The substance should be stored in a well-ventilated area, and work should be conducted in a fume hood to minimize exposure. Spills should be handled with caution, using appropriate cleanup materials. Refer to the safety data sheet (SDS) for detailed emergency procedures and storage guidelines.
