Conclusions:
The boiling point of test item 1-[(2-hydroxyethyl)thio]propan-2-ol was determined as 270 ºC at 101.325 kPa after applying the Clapeyron-Clausius equation.
Executive summary:

A study was undertaken to determine the boiling point of test item 1-[(2-hydroxyethyl)thio]propan-2-ol. The test was performed according to OECD Guideline 103 (Boiling Point) using an ebulliometer technique, in which the liquid is heated under equilibrium conditions at atmospheric pressure and exact boiling temperature noted when the liquid begins to boil. After the Clausius-Clapeyron equation was applied, the boiling point of the substance was reported as 270 ℃ at 101.325 kPa.
