APAB - Introduction

Aminobenzoic acid p-aminophenyl Ester, chemical formula C8H9NO2, is an organic compound. Its properties are as follows:

Physical Properties:
Appearance: Colorless to light yellow crystalline or crystalline powder
Solubility: Soluble in alcohol, ether and ketone, slightly soluble in water

Chemical Properties:
p-aminophenyl aminobenzoate is an acidic substance that can react with alkali in water to form a salt. It can also undergo esterification and can be reduced to the corresponding p-aminobenzoic acid.

Application:
p-Aminophenyl aminobenzoate is often used as an intermediate in organic synthesis, especially in the fields of dyes, drugs and pesticides. It can also be used as a raw material for rubber antioxidants and optical brighteners.

Method:
p-aminophenyl aminobenzoate can be prepared by reacting p-aminobenzoic acid with an anhydride to form an ester.

Safety Information:
p-aminophenyl aminobenzoate has an irritating effect on the eyes, skin and respiratory system. Rinse with plenty of water immediately after contact. Avoid inhalation of dust and prolonged contact with the skin during use. Long-term exposure may have adverse effects on physical health. During storage and use, care should be taken to avoid contact with oxidants, acids and alkalis to prevent dangerous reactions.
