Any other information on results incl. tables

A test substance sample was observed to be a gritty, medium and coarse, white crystalline 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 and agglomerated particles.

Applicant's summary and conclusion

Conclusions:
The substance is a white crystalline powder at room temperature.
