Chemical Name or Material: 1,1,3,3-Tetramethylguanidine
Basicity / reactivity: TMG is an exceptionally strong, largely non-nucleophilic base — useful for deprotonations, promoting condensations, and catalyzing reactions where nucleophilic attack by the base would be undesirable.
Stability / sensitivity: The neat base is stable under typical handling but is air-sensitive toward CO₂ (absorbs CO₂/acidic gases); it should be stored under inert atmosphere or tightly sealed to avoid uptake of CO₂ and moisture.
It is incompatible with strong oxidizers and strong acids (which protonate it).
Thermal behaviour: Relatively low volatility at ambient conditions, but will boil at elevated temperature; decomposition products on heating may include nitrogen oxides / irritant fumes typical for nitrogenous organics — follow SDS guidance.
