6-Aminouracil Chemical Properties,Usage,Production
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.
Synthesis
105-56-6
57-13-6
873-83-6
GENERAL METHOD: Ethyl cyanoacetate (0.1 mol) was mixed with urea, methylurea and/or methylthiourea (0.1 mol) in anhydrous ethanol (290 mL) containing sodium. The reaction mixture was refluxed for 10-12 hours and subsequently cooled to room temperature. Acidification was carried out by adjusting the pH to 6 with acetic acid. The resulting precipitate was washed with distilled water and dried in a desiccator overnight.1a was obtained in 69% yield with a melting point over 360°C (literature value ≥ 360°C).
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.]
