Applicant's summary and conclusion

Conclusions:
Ethyl 3-hydroxypropanoate was determined to below (-50.0 ± 0.5) ℃ {below (223.2 ± 0.5) K}.
Executive summary:

The freezing point of Ethyl 3-hydroxypropanoate was measured by Freezing point apparatus. The measurable range with the freezing point apparatus is from room temperature to – 50 ℃, and Ethyl 3-hydroxypropanoate could be stirred without freezing to -50.0 ℃.
Average of freezing point: below (-50.0 ± 0.5) ℃ {below (223.2 ± 0.5) K}
