3-Nitrophthalic Anhydride CAS 641-70-3

1. 3-Nitrophthalic anhydride is primarily used as a key intermediate in the synthesis of dyes, pigments, and fluorescent whitening agents.
2. 3-Nitrophthalic anhydride CAS 641-70-3 serves as a monomer or building block for high-performance polymers, such as nitro-substituted polyimides and epoxy resins.
3. This compound is also utilized in the production of pharmaceuticals, agrochemicals, and specialty chemicals.

1. Store 3-nitrophthalic anhydride in a cool, dry, well-ventilated place, protected from moisture and away from heat, sparks, open flames, and combustible materials.
2. Keep the container tightly closed and separated from strong oxidizing agents, strong bases, reducing agents, and metals.
3. Handle 3-Nitrophthalic anhydride CAS 641-70-3 with appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety goggles, and a dust mask. Use a fume hood to avoid inhalation of dust.

1. Isolate the spill area, restrict access, ensure ventilation, and wear full protective gear (gloves, goggles, protective clothing, respirator suitable for dust).
2. **Do not sweep.** Carefully collect 3-Nitrophthalic anhydride CAS 641-70-3 with a damp cloth or a vacuum cleaner equipped with a HEPA filter. Place all contaminated material in a sealed, labeled container for hazardous waste disposal.
3. Prevent the material from entering drains, sewers, or the environment. Decontaminate surfaces with water and detergent, collecting washings for disposal. Contaminated absorbents may present a fire risk.

1. 3-Nitrophthalic anhydride is harmful if swallowed, inhaled, or in contact with skin. It causes severe skin burns, eye damage, and respiratory irritation. It is corrosive and moisture-sensitive.
2. 3-Nitrophthalic anhydride CAS 641-70-3 is a combustible solid and may explode if heated under confinement. Nitro compounds can be shock-sensitive. It may emit highly toxic and corrosive fumes (nitrogen oxides, phthalic anhydride derivatives) when heated.
3. Always consult the official 3-nitrophthalic anhydride Safety Data Sheet (SDS) for the most current and comprehensive hazard, handling, and regulatory information. Handle with extreme caution due to its combined corrosive, toxic, and potential explosive hazards.
