4-cyano-2-nitrophenolate - Introduction
It is an organic compound with the molecular formula C7H4N2O3 and the structural formula OH NO2C6H3CN.
Nature:
is a yellow crystal with a bitter taste. It is sparingly soluble in water and can be dissolved in organic solvents such as alcohols and ethers.
Use:
It is often used as an intermediate in organic synthesis and can be used to prepare other organic compounds, such as drugs and dyes.
Method:
can be obtained by reacting p-dinitrobenzonitrile with sodium hydroxide. First, the dinitrobenzonitrile is converted to sodium 4-hydroxy-3-nitrobenzoate with sodium hydroxide under alkaline conditions. Then, under acidic conditions, the acid is added to convert it.
Safety Information:
It is a toxic compound and should be handled with care. When in use, wear appropriate protective equipment to avoid skin contact and inhalation of dust. Avoid contact with strong oxidants and combustibles. When storing and handling, it is necessary to observe the relevant safety regulations. If swallowed or touched, seek medical attention immediately.
