2-Chloro-7-nitroquinoxaline(CAS: 55686-94-7)

2-Chloro-7-nitroquinoxaline is a crystalline solid with a molecular weight of approximately 244.59 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. The compound is moderately reactive, particularly towards nucleophiles and reducing agents. It is stable under normal storage conditions but should be handled with care to avoid decomposition.

2-Chloro-7-nitroquinoxaline is typically synthesized by the reaction of 2-aminoquinoxaline with thionyl chloride followed by nitration with nitric acid. The reaction involves the introduction of a chlorine atom and a nitro group into the quinoxaline ring. The process requires careful control of reaction conditions to ensure high yield and selectivity.

2-Chloro-7-nitroquinoxaline has applications in the pharmaceutical industry, where it serves as a precursor for synthesizing various drugs. It is also used in the sensor industry for the development of gas sensors and in the semiconductor industry for specific applications related to doping or as a precursor material.

When handling 2-Chloro-7-nitroquinoxaline, it is essential to wear appropriate personal protective equipment (PPE) including gloves, safety goggles, and a lab coat. Work should be conducted in a fume hood to minimize exposure. Spills should be handled with care, using appropriate cleanup procedures, and the material safety data sheet (MSDS) or safety data sheet (SDS) should be consulted for detailed handling instructions.
