Guanidinium bicarbonate (or GdmHCO3) is a colorless organic salt, with the formula C(NH2)3HCO3.
Contents
Properties
Chemical
Guanidinium bicarbonate reacts with acids to form guanidinium salts and releasing carbon dioxide.
Addition of guanidine freebase to a solution of guanidinium bicarbonate will form guanidinium carbonate.
- C(NH2)3HCO3 + HNC(NH2)2 → (C(NH2)3)2CO3
Physical
Guanidinium bicarbonate is a white solid.
Availability
Guanidinium bicarbonate is sold by some chemical suppliers.
Preparation
Guanidinium bicarbonate can be prepared by bubbling carbon dioxide in a solution of guanidine freebase or guanidinium carbonate.
Leaving solutions of guanidinium bicarbonate in open air will cause them to absorb more carbon dioxide, resulting in guanidinium bicarbonate.
Projects
- Make guanidine salts.
Handling
Safety
Guanidinium bicarbonate has low toxicity, though it should be handled with care, as it's irritant.
Storage
In closed, air-tight containers.
Disposal
No special disposal is required.
