Description of key information

The density of CAS# 756-12-7 is 1.57 g/cm3 at 20.0 °C

Key value for chemical safety assessment

Additional information

The density of CAS# 756-12-7 was evaluated in two studies. The key study was conducted in accordance with OECD TG 109 and is compliant with GLP standards. Therefore this study is classified as reliable without restrictions. In another study, density was determined to be 1.56 g/cm3 at 20.0 °C which supports the key study results. The supporting study incorporates data from two methods into one data set. Although not stated, the supporting study appears to be conducted according to OECD TG 109, but the key study is the preferred value due to the supporting study's deviations from OECD TG 109 and non-GLP compliance.
