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

One GLP Guideline study is available investigating the short-term effects of 1,3-butylene diacetate (CAS 1117-31-3) to fish (Vryenhoef, 2012). The study was performed according to OECD 203 with the rainbow trout Oncorhynchus mykiss. Test concentrations of 10, 18, 32, 56 and 100 mg/L were applied and verified analytically by GC/FID. Since measured concentrations did not differ by more than 20%, the effect concentrations were based on the nominal test concentrations. After 96 h 14% mortality was reported at a concentration of 32 mg/L, whereas 100% mortality was observed at concentrations of 56 and 100 mg/L, respectively. Thus, a LC50 (96 h) of 39 mg/L was calculated.
