Properties and stability

Avoid contact with oxidizing agents.

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Keep container tightly sealed. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

It is obtained by reducing 3-nitro-aminomethyl ether with iron powder. Add 60% acetic acid and 3-nitro-p-aminoanisole into the reduction kettle, stir for 0.5h, and add iron powder. Heat to 60°C and keep the reaction until the liquid seepage zone is colorless, which is the end point, and 4-methoxy o-phenylenediamine is generated by reduction.

Purpose

Dye intermediates. Used in the production of dye dispersed fluorescent yellow Ⅱ.
