Key result
Melting / freezing pt.:
< -10.38 °C
Remarks on result:
other: no other details mentioned
Conclusions:
The Freezing point of 1,4-dimethyl-5-[[4-[methylbenzylamino]phenyl]azo]-1H-1,2,4-triazolium acetate was determined. No freezing was observed up to -10.38 °C. Hence, the freezing point was inferred to be less than -10.38°C.
Executive summary:

The Freezing point of 1,4-dimethyl-5-[[4-[methylbenzylamino]phenyl]azo]-1H-1,2,4-triazolium acetate was determined. No freezing was observed up to -10.38 °C. Hence, the freezing point was inferred to be less than -10.38°C.
