Triglycine Sulfate
Formula: 3(NH2CH2COOH)·H2SO4
Properties
- Crystal system: monoclinic
- Stability on air: stable
Triglycine sulfate has an interesting physical property: strong birefringence:
Preparation
Dissolve glycine and sulfuric acid in water, in 3:1 molar ratio, then crystallize.
Growing
Regular slow evaporation method used. Solubility is not much different from pure glycine, around 20..30g per 100ml.
Safety
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.
