Description of key information
The melting point of N-cyclohexylbenzothiazole-2-sulphenamide was determined in a series of experimental studies:
Kirk-Othmer, 2000: 94 - 102 °C
Tang et. al., 2019: 98 - 100 °C
Dou et. al., 2017: 94 - 96 °C
CRC Handbook of Chemistry and Physics, 97th Edition, 2017: 103 °C
In conclusion, the melting point is sufficiently described between 94 - 103 °C for further assessment.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 99 °C
