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

The melting range of the substance 1,2-Benzenediol, 3,5-dialkyl-, 1,2-dicarboxylate was determined according to OECD 102 resp. EU A.1. Two batches with different purities (> 99.85% and > 99%) were tested. There was no decomposition observed from the measurment of sample with high purity. However the decomposition of the sample with the low purity was observed. This is probably due to the impurities.
