Introduction

Quinazoline is an organic compound. Here are the details about quinazoline:Quality:Quinazoline is a colorless to light yellow crystalline or crystalline powder;Soluble in alcohols, ethers and ammonia, insoluble in water;Quinazoline is stable in air but tends to produce nitroso compounds when exposed to light.Use:Quinazoline can also be used in the synthesis of dyes, rubber additives, and photosensitive materials.Method:Quinazoline can be prepared by the following reaction pathways:pyrazine reacts with chlorine to form 2,3-dichloropyridine, and then reacts with ammonia to form 2-amino-3-chloropyridine;2-amino-3-chloropyridine is reacted with ketones or alcohols and dehydrated to form quinazoline.Safety Information:Quinazoline has an irritating effect on the skin, eyes, and respiratory tract and should be rinsed with water immediately after exposure. Avoid inhalation and ingestion;During the use of quinazoline, personal protective measures should be taken, gloves, goggles and masks should be worn;When storing quinazoline, it should be kept away from ignition and oxidant, and kept sealed;When using or disposing of quinazoline, follow relevant regulations and safe operating guidelines.
