[Typical Properties]

Colorless crystals (often containing third or fifth grade crystalline water) are highly hygroscopic and can quickly absorb carbon dioxide in the air.They decompose into methanol and trimethylamine at 130 ° C. Typically, solutions containing 10% or 25% water (or alcohol) and crystalline water compounds 

are used.
