2-Chloro-5-nitro-3-(trifluoromethyl)pyridine(CAS: 99368-67-9)

2-Chloro-5-nitro-3-(trifluoromethyl)pyridine is a crystalline solid with a molecular weight of approximately 265.01 g/mol. It is slightly soluble in water and readily soluble in organic solvents like ethanol and acetonitrile. Chemically, it exhibits high reactivity due to the presence of both a nitro and a chloro substituent, making it prone to redox reactions. It has a melting point of around 175-178°C and a boiling point of approximately 300°C. It is stable under normal conditions but should be handled with care due to its reactivity.

2-Chloro-5-nitro-3-(trifluoromethyl)pyridine can be synthesized via a multi-step process involving Friedel-Crafts alkylation and nitration of 3-chloro-5-(trifluoromethyl)pyridine. The key steps include the use of aluminum chloride as a catalyst for the alkylation, followed by the nitration using nitric acid and sulfuric acid. The yield is typically around 80%, with high selectivity towards the desired product.

2-Chloro-5-nitro-3-(trifluoromethyl)pyridine is primarily used in the pharmaceutical industry as an intermediate in the synthesis of various drugs. It is also employed in the production of sensors and materials for electronic devices. Its high reactivity and specific functional groups make it valuable in these applications, although its use is limited due to its reactivity and potential hazards.

When handling 2-Chloro-5-nitro-3-(trifluoromethyl)pyridine (CAS: 99368-67-9), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be handled in a well-ventilated area or a fume hood to minimize exposure to fumes. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. A safety data sheet (SDS) should be consulted for detailed guidance on handling and storage. Due to its reactivity, it should be stored in a cool, dry place away from sources of ignition and incompatible materials.
