Any other information on results incl. tables
A test substance sample was observed to be a medium to fine off-white powder with clusters. At 100x magnification under a microscope, the particles appeared to be irregular shaped crystals. At 400x magnification, the sample was observed to be made up of single crystalline particles.
Applicant's summary and conclusion
- Conclusions:
- The substance is an off-white powder at room temperature.
