4-Nitroaniline：yellow solid with a mild odor. Sinks in water.p-Nitroaniline consists of yellow crystals with a pungent, faint ammonia-like odor.Bright yellow crystalline powder or flakes with a faint, ammonia-like, slightly pungent odor. Combustible.
4-Nitroaniline (also known as p-nitroaniline) is an organic compound with bifunctional groups of amino and nitro groups. It appears as yellow needle-like crystals, slightly soluble in cold water, and soluble in hot water, ethanol, and benzene. It is an important intermediate in dyes, pesticides, and antioxidants, but it is highly toxic and can easily cause severe blood poisoning.
Application of 4-Nitroaniline:
Product of chromogenic reactions.
4-Nitroaniline is used in the synthesis of photorefractive polymers, as novel chromophores in analytical study. As well, due to the absorption spectrum associated with 4-Nitroaniline, it is used to de termine catechol derivatives in syntheses.
Dyestuff intermediate.
