Applicant's summary and conclusion

Conclusions:
Melting point was determined by a scientifically reasonably study according to DIN 51007 and ASTM D 3418-99, so there is no reason to conclude that the results are not reliable. Melting point of (S)-(4,5-dihydro-5-thioxo-1,3,4-thiadiazol-2-yl)benzenecarbothioate was determined as 226 °C.
Executive summary:

The melting point of (S)-(4,5-dihydro-5-thioxo-1,3,4-thiadiazol-2-yl) benzenecarbothioate was determined according to DIN 51007 and ASTM D 3418-99 by DSC (differential scanning calorimetry) and defined to be 226 °C.
