Applicant's summary and conclusion

Conclusions:
The melting temperature of this sample was identifed and the thermal mecoposition of the sample occured before boiling temperature was identified within 50 ℃ ~ 500 ℃ at 101.325 kPa. Therefore, it was impossible to identify the boiling temperature of the test sample 'L-Ascorbic acid,2-O-alpha-D-glucopyranosyl-’ provided by the client due to the thermal decomposition.
