Applicant's summary and conclusion
- Conclusions:
- The melting point/melting range of’ UC—136 was determined using the
capillary method. The temperature at the beginning and at the final stage
of the melting process of’ UC—136 was determined to be 350.5 K (77.3°C) and
351.8 K (78.6°C), respectively. During the melting process, the test
substance changed from a white, somewhat slightly—pink coloured solid into
a dear, slightly—pink coloured liquid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
