- 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
- Decomposition:
- yes
- Remarks:
- Color changed from white to light brown
- Decomp. temp.:
- 289.5 °C
- Conclusions:
- The substance decomposes at a temperature of 289.5 °C before boiling.
- Executive summary:
In a GLP guideline study, the boiling 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 830.7220, OECD TG 103, and EC method A2. This procedure was repeated with the test substance to obtain two measurements. The substance decomposes at a temperature of 289.5 °C before boiling as indicated by a color change from white to light brown.
