Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
It is consiedered that the LD50 for Thiazole Derivative by gavage is over 2000 mg/kg in the rat, though the test article caused mastication-like repetitive movement of the jaw followed by staggering gait.
