Precautions
3-Hydroxy-3H-1,2,3-triazolo[4,5-b]pyridine is stable, not hygroscopic, and can be stored indefinitely. HOAt (3-Hydroxy-3H-1,2,3-triazolo[4,5-b]pyridine) solutions in DMF (0.3 M) can be stored in an inert atmosphere for weeks. Syntheses of peptides carried out with freshly prepared and 4-week-old solutions show similar quality to the crude product. Violent decomposition may occur when dried at elevated temperatures.
