59290-82-3 - Introduction
3-Nitroisonicotinic acid is also known as 3-Nitroisonicotinic acid, the chemical formula is C6H4N2O5.
Nature:
3-Nitroisonicotinic acid is a solid in the form of yellow crystals. It has strong acidity. The compounds have low solubility in water, but are soluble in organic solvents such as alcohols and ketones.
Use:
3-Nitroisonicotinic acid is mainly used as an intermediate in organic synthesis. It can be used to synthesize various organic compounds containing nicotine structure, such as drugs, dyes and flame retardants.
Preparation Method:
3-Nitroisonicotinic acid is typically obtained by nitration of 4-pyridine carboxylic acid. Nitration is a common reaction for introducing nitro groups into organic compounds. A mixture of nitric acid and sulfuric acid is usually used as nitrating agent.
Safety Information:
3-Nitroisonicotinic acid may be irritating to the skin, eyes, and respiratory system. When handling this compound, care should be taken to avoid direct contact to prevent injury. At the same time, in the operation to maintain good ventilation conditions, to avoid inhalation of the substance of the vapor. In case of contact with this substance, wash it immediately with water and consult a doctor for relevant first aid measures.
