- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
Enantiomers do not differ in their physical properties except for their optical activity. Their chemical properties are also identical except for their ability to react in stereoselective reactions.
Therefore, it is scientifically justified to use the data from L-2-hydroxy-2-phenylacetic acid (CAS 611-71-2) as a source substance to describe the target substance D-2-hydroxy-2-phenylacetic acid (CAS 17199-29-0)

The regression of the results leads with a mean deviation of < 20 % to the following equation:
ln(p/hPa) = 34.5492 - 16489.22 / (273.15 + t/°C)
The vapour pressure at 20 °C, 25 °C and 50°C was calculated from the regression equation.
