Additional information

A study performed according to OECD guideline 103 reports a broad range of boiling in the 290 - 350 °C region. The mean onset is selected as giving the best value of the boiling point. The difference between the lower onset value and the higher peak value is used to estimate the uncertainty. The boiling point of Propylparaben is 301 ± 16 °C.
