- Crystal system: monoclinic
- Stability on air: stable
Triglycine sulfate has an interesting physical property: strong birefringence:
Dissolve glycine and sulfuric acid in water, in 3:1 molar ratio, then crystallize.
Regular slow evaporation method used. Solubility is not much different from pure glycine, around 20..30g per 100ml.
The compound is not toxic, but since glycine is a very weak base, its solution is very acidic. Thus, it have corrosive and irritating properties, and even can cause burns.
