2,5-Dichloropyrimidine Chemical Properties,Usage,Production

Uses

2,5-Dichloropyrimidine acid is employed as a important raw material and intermediate used in organic synthesis agrochemical, pharmaceutical and dyestuff field.

Preparation

2,5-Dichloropyrimidine was synthesised from 2-hydroxypyrimidine hydrochloride by treatment with aqueous chlorine solution. Reaction of the product with phosphoryl chloride in the presence of N,N-dimethylaniline gave the desired product in 40% yield. The sample was then purified by sublimation.

storage

Store in cool, dry place in tightly closed container. With adequate ventilation. Store away from oxidizing agent.

structure and hydrogen bonding
