Solubility: Poorly soluble in water, readily soluble in ethanol, ether , and benzene.

1. Avoid light exposure and contact with strong oxidizers.
2. White to yellowish-brown crystalline flakes
3. Soluble in hot water, ethanol , ether, and benzene, slightly soluble in cold water,
4. Susceptible to oxidation in air, leading to darkening toxic.

Store in a cool, well-ventilated area away from heat, open flames, and direct sunlight. Keep sealed and separate from oxidizers and food-grade chemicals. Equip storage areas with appropriate firefighting equipment and leak containment materials.

Synthesized by condensation of aniline and formaldehyde in hydrochloric acid at 50-60℃,followed by neutralization with sodium carbonate solution, separation, distillation, and crystallization.

1. Epoxy Resin curing agent:
2. Antioxidant and Anti-aging agent: used in rubber and latex product
3. Polymer production:Key monomer for polyurethanes, diisocyanates, polyamides, and heat-resistant polymers; applied in high-temperature coatings, aerospace materials, electrical insulation( like wire enamels, laminates), and synthetic resins
4. Vulcanization accelerator for chloroprene rubber
5. Raw material for corrosion inhibitors, and specialty chemicals
6. Analytical reagent
