White to Off-White Crystalline Solid

Uses

6-Methyluracil (cas# 626-48-2) is a compound useful in organic synthesis.

Preparation

6-Methyluracil [626-48-2]. is produced by condensation of diketene with urea. It is used in the production of the analgesic mepirizole, the feed additive orotic acid, and 5-aminoorotic acid.

Definition

ChEBI: A pyrimidone that is uracil with a methyl group at position 6.

Safety Profile

Moderately toxic by ingestion. Questionable carcinogen with experimental neoplastigenic and teratogenic data. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Crystallise 6-methyluracil from EtOH or acetic acid. [Beilstein 24 III/IV 1281.]
