- Specific details on test material used for the study:
- Composition: Reaction mass of dipotassium 3,3’-sulphonylbis(benzenesulphonate) and potassium 3-(phenylsulphonyl)benzenesulphonate
Purity: 92.8%
CAS# 63316-33-6 and 63316-43-8
Physical Description: White powder
Stability: Test substance was expected to be stable for the duration of testing.
Expiration Date: December 31, 2018 - Key result
- Melting / freezing pt.:
- 238.3 °C
- Atm. press.:
- 1 Torr
- Conclusions:
- The melting point was determined to be 238.3 °C
- Executive summary:
In a GLP guideline study, the melting point of the test substance was measured by the capillary technique using the Stuart SMP20 Melting Point Apparatus based on the procedures described in OPPTS 830.7200, OECD TG 102, and EC method A1. This procedure was repeated with the test substance to obtain two measurements. The temperature during this test reached 238.3 °C.
