Introduction

3-Amino-5-(4-phenoxyphenyl)-4-cyano-1H-pyrazole, also known as AAPP, is an organic compound. The following is an introduction to its properties, uses, manufacturing methods and safety information:Quality:- Appearance: AAPPs are usually white or off-white crystals, and the amorphous material is a pale yellow solid.- Solubility: AAPP can be dissolved in some organic solvents (such as ethanol, dimethyl ether, acetone, etc.), but it is less soluble in water.Use:Method:- In chemistry labs, AAPPs are typically prepared in a two-step reaction. 4-phenoxybenzoic acid reacts with aminoacetonitrile to obtain 4-phenoxyphenyl formylamide, and then the product is reacted with potassium cyanide to form AAPP.Safety Information:- AAPPs are chemicals and need to be handled and stored with care.- Personal protective equipment such as laboratory gloves and glasses should be used during the procedure to avoid contact with skin and eyes.- When handling AAPP, it should be done in a well-ventilated area and avoid inhaling its volatiles.- Follow local safety practices and dispose of waste appropriately.
