Introduction

2-Aminopyrimidine is an organic compound. It is a white crystal, weakly alkaline, soluble in water, alcohols and some organic solvents.It can also be used to make dyes, rubber flame retardants, pesticides, etc.There are several methods for the preparation of 2-aminopyrimidine, and the most common method is to prepare it by ammoniating 4-cyanopyrrole. The specific step is to react 4-cyanopyrrole with ammonia gas to generate 2-aminopyrimidine.Safety Information: 2-Aminopyrimidine is stable at room temperature, but may decompose at high temperatures. It is a flammable compound and should be avoided in contact with strong oxidizing agents. Personal protective equipment such as gloves, goggles, and a lab coat should be worn during handling. Care should be taken to avoid inhalation, skin contact, and swallowing. When storing, it should be kept in a cool, dry place, away from fire and combustibles.
