Additional information

Vapour pressure of 1,2,4-triazole was measured using the effusion method in compliance with the OECD Guidelines for the Testing of Chemicals No. 104, and was calculated using Advanced Chemistry Development (ACD/Labs) Software V8.14. The vapour pressure values were reported as 2.15E-4 kPa (0.215 Pa) at 20°C (293.15 K) and 2.03E-2 Torr (2.706 Pa) at 25°C (298 K), for measured and calculated values, respectively.
