Description of key information
The melting point range of MTDID 28460 is 110.6 °C to 123.2 °C, as determined according to OECD TG 102.
Key value for chemical safety assessment
Additional information
The melting point range of MTDID 28460 is 110.6 to 123.2 °C. The range was determined using a digital melting point apparatus. The study was conducted according to OECD TG 102 and was CLP compliant; therefore the study is considered reliable without restrictions.
A melting point of 92 °C to 104 °C was also reported on a Safety Data Sheet which cited the DIN 53101 standard. No other details were reported on the Safety Data Sheet, and the study report was not available for review, therefore the reliability of this data is not assignable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
