Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

A melting point study was conducted according to Regulation (EC) No 440/2008 method A.1 and OECD TG 102. The melting point of Cyanuric chloride has been measured by capillary method. The melting range of cyanuric chloride was determined to be 146.5 -147.5°C corresponding to 419.65 - 420.65 K. Six different publications show the same value compared to the key study for the melting point of cyanuric chloride. This value is thus regarded as reliable. Because it results from a study according to Regulation (EC) No 440/2008 method A.1, the measured value in the key study is taken as key parameter.
