Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guideline
according to guideline
other: JSQI (The Japanese Standards of Quasi-drug Ingredients), Melting Point Measurement Method 2
Principles of method if other than guideline:
Melt carefully the sample at temperature as low as possible, and, taking care to prevent bubbling, draw it into a capillary tube about 120 mm long, which is left open at both ends, to a depth of about 10 mm.
Allow the charged tube to stand for 24 hours at a temperature not exceeding 10°C, or for not less than 2 hours in contact with ice, holding the tube not to allow the elution of the sample from it.
Then attach the tube to the thermometer (No.1) by means of a rubber band so that the sample is on a level with the middle part of the mercury bulb. Adjust the tube in a water-containing beaker to such a position that the upper edge of the sample is 10 mmm below the water level.
Heat the beaker with constant stirring until a temperature 5°C below the expected melting point is attained. Then regulate the rate to 1°C per minute. The temperature at which the sample is observed to rise in the capillary tube is taken as the melting point.
