Product Introduction
4-Nitroaniline (CAS 100-01-6), also widely known as p-Nitroaniline or 1-amino-4-nitrobenzene, is an organic compound with the formula C6H6N2O2. It appears as a bright yellow to orange crystalline powder. It is a derivative of aniline, carrying a nitro group in the para position. 4-Nitroaniline (CAS 100-01-6) is an essential raw material in the chemical industry, valued primarily for its role in the synthesis of a vast range of azo dyes and pigments. It is sparingly soluble in water but dissolves readily in most organic solvents like ethanol, ether, and benzene.

Storage
4-Nitroaniline is toxic and sensitive to light. It must be stored in a cool, dry, and dark warehouse away from direct sunlight. Keep containers tightly sealed to prevent dust generation and moisture absorption. Store in a dedicated area for toxic substances, away from food, feed, and oxidizing agents. Proper ventilation is essential to prevent the accumulation of dust. Properly stored, it has a shelf life of 24 months.
