Reference
From comparison of the endotherm profiles obtained from samples analyzed using perforated crucible lids (which allow self-pressurization up to the boiling point) and those using manually pierced crucible lids (i.e. an open system), it can be confirmed that the observed thermal event was a true boiling point for the test item. This was since the open system allowed premature evaporation of the test item during heating, resulting in a broader endotherm, with a typically lower and more variable extrapolated onset temperature.
The pre‑perforated crucible lids however, which contain a consistent 50 µm perforation achieved by laser drilling, retained the initial vapor within the crucible, until the exponential increase in pressure as the boiling point was reached. It is for this reason that only the results obtained from the perforated crucible lid determinations, runs 1 and 2, were used for the quantification of the boiling point.
The use of manually pierced crucibles (an open system)alsoprovided an opportunity to assess the stability of the test item in air and in an inert atmosphere (nitrogen). In both cases the test item vaporized (boiled) completely withlittle or no residues remaining. Differences between the thermogram profiles in the two atmospheres may have originated from variability in the size of the manually pierced holes and the change from a static air atmosphere, to a flowing nitrogen atmosphere, both of which would influence the onset and rate of vaporization of the test item.

Additional information
The determination of boiling point of Jasminlactone was carried out by differential scanning calorimetry. The procedure was designed to be compatible with the EC Method A.2 and the OECD test guideline 103, and was conducted in compliance with GLP.
The boiling point of the test item has been determined to be 292.2 ± 0.5 °C (565.4 ± 0.5 K) at 102.4 kPa.
