Guanidine exists protonated, as guanidinium, in solution at physiological pH. Guanidinium chloride (also known as guanidine hydrochloride) has chaotropic properties and is used to denature proteins. Guanidinium chloride is known to denature proteins with a linear relationship between concentration and free energy of unfolding.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Guanidinium chloride is a weak acid with a pK a of 13.6. The reason that it is such a weak acid is the complete delocalization of the positive charge through three nitrogen atoms (plus a little bit of positive charge on carbon).
Melting point: −30 °C (−22 °F; 243 K) Boiling point: 160 to 162 °C (320 to 324 °F; 433 to 435 K) Solubility in water. Miscible Vapor pressure: 30 Pa (at 20 °C)
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Melting point: 216 °C (421 °F; 489 K) ... Guanidine nitrate is the chemical compound with the formula [C(NH 2) 3]NO 3. It is a colorless, water-soluble salt.
