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

Water stability has been determined for 2-dimethylaminoethyl methacrylate using a OECD Guideline study. The results showed that in contact with water 2-dimethylaminoethyl methacrylate will hydrolyse slowly under environmental conditions (t1/2 = 4 days at pH 7, t1/2 = 3.2 hours at pH 9). At pH 4 no hydrolysis was observed. Hydrolyse products were methacrylic acid (CAS# 79-41-4) and 2-dimethylamino ethanol (CAS# 108-01-0). Furthermore, a calculated half-life of 3.9 hours indicates that after evaporation or exposure to the atmosphere, the substance will be rapidly degraded by photochemical processes.
