Guanidinium bicarbonate (or GdmHCO3) is a colorless organic salt, with the formula C(NH2)3HCO3.

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.

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.

Storage

In closed, air-tight containers.

Disposal

No special disposal is required.
