| | 2,5-Dichloropyrimidine Usage And Synthesis |
| 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 | C4H2Cl2N2, M=148.98 monoclinic, space
