1,3,5‐Triazine
2008
[290-87-9] C3H3N3 (MW 81.09)
InChI = 1S/C3H3N3/c1-4-2-6-3-5-1/h1-3H
InChIKey = JIHQDMXYYFUGFV-UHFFFAOYSA-N
(C1 electrophile; formylating agent;2 methylenating and aminomethylenating agent;3 in combination with cyclic amines, dehydro-Mannich bases4, 5 are formed)
Alternate Name: s-triazine.
Physical Data: mp 80–82 °C (very pure: 85–86 °C); bp 114 °C; d 1.38 g cm−3.
Solubility: sol alcohol, ether, most organic solvents; 1 g dissolves freely in 10 mL methanol.
Form Supplied in: white solid; widely available.
Handling, Storage, and Precautions: very volatile; hygroscopic and very sensitive to solvolysis in water, alcohols, and solvents with OH groups. Distillation over sodium for purification has to be done cautiously to avoid overheating at the end, otherwise triazine–sodium compounds are formed which can lead to explosive decomposition of triazine.1
