Additional information
There is one reliable key study for this endpoint. In this study (Habeck C., 2010), the vapor pressure of Reaction mass of Dimethyl adipate (CAS627-93-0), Dimethyl glutarate (CAS1119-40-0) and Dimethyl succinate (CAS106-65-0) was determined according to the EECDirective 92/69, A.4 (2008), to the OECD guideline No. 104, (2006) and to the Council Regulation EC No. 761/2009, A4 (2009) using the gas saturation method. The study was compliant with the GLP principles.
The vapor pressure of Reaction mass of Dimethyl adipate (CAS627-93-0), Dimethyl glutarate (CAS1119-40-0) and Dimethyl succinate (CAS106-65-0) was measured at test temperatures of 30 °C, 40 °C and 50 °C and was determined to be

Calculation of the vapor pressure at 25 °C by extrapolation based upon the simplified Clausius-Clapeyron equation resulted in a vapor pressure of :
Dimethyl adipate: 0.47 Pa at 25 °C
Dimethyl glutarate: 8.5 Pa at 25 °C
Dimethyl succinate: 9.4 Pa at 25 °C.
