Aminoguanidine, also known as pimagedine, is an organic base, a derivate of guanidine.
Contents
Properties
Chemical
Aminoguanidine is highly basic, and will readily absorb carbon dioxide forming aminoguanidine carbonate/bicarbonate.
Physical
Aminoguanidine is a white solid.
Availability
Pure aminoguanidine is difficult to find, but its salts are more readily available.
Preparation
Aminoguanidine can be prepared from calcium cyanamide and hydrazine sulfate. Reaction produces aminoguanidine carbonate. To obtain the free base, a strong base, like sodium methoxide is added.[1]
Aminoguanidine canso al be prepared by reducing nitroguanidine with zinc powder in acetic acid.[2] Reaction produces aminoguanidine acetate, which can be converted into pure base by dissolving the solid in another solvent, then adding a strong base, like sodium methoxide.
Projects
- Make aminoguanidinium nitrate
- Make tetrazoles
Handling
Safety
There is little information about the toxicity of this compound and its salts. Pimagedine, like other guanidine derivates, has been investigated in the treatment of diabetes, more specifically diabetic kidney disease.
Storage
In closed bottles.
Disposal
No special disposal is required. Can be poured down the drain.
