What is 6-Aminouracil ?
Chemical properties
cream to light brown crystalline powder
Definition
ChEBI: 6-aminouracil is a pyrimidone.
Safety Profile
Moderately toxic by parenteralroute. When heated to decomposition it emits toxic fumesof NOx.
Purification Methods
Purify the aminouracil by dissolving it in 3M aqueous NH3, filtering hot, and adding 3M formic acid until precipitation is complete. Cool, filter off (or centrifuge), wash well with cold H2O, then EtOH and dry it in air. Dry it further in a vacuum at ~80o. [Barlin & Pfeiderer J Chem Soc (B) 1424 1971, Beilstein 25 III/IV 4107.]
