2-Amino-4-nitrophenol

Description:

2-Amino-4-nitrophenol, with the CAS number 99-57-0, is an organic compound characterized by the presence of both amino and nitro functional groups attached to a phenolic ring. This compound typically appears as a yellow to orange crystalline solid and is soluble in water and organic solvents, reflecting its polar nature due to the functional groups. It has a melting point that generally falls within a specific range, indicating its solid state at room temperature. The amino group (-NH2) contributes to its basicity, while the nitro group (-NO2) is known for its electron-withdrawing properties, influencing the compound's reactivity and stability. 2-Amino-4-nitrophenol is often utilized in various applications, including as a dye intermediate, in the synthesis of pharmaceuticals, and in analytical chemistry as a reagent. However, it is important to handle this compound with care due to potential toxicity and environmental concerns associated with nitro compounds. Proper safety measures should be observed when working with this substance in laboratory settings.
