The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

One reliable study provides boiling point measurements of pure and anhydrous hexamethylene diamine, using Differential Scanning Calorimetry. The method can be related to OECD103 guidelines, but some aspects of method are unclear (justifying Klimisch score of 2, and not 1). The study was not conducted under GLP, but nevertheless with obvious scientific considerations for quality.

This result is supported by numerous literature data which could not be assigned in most cases, and pressure is not indicated, however all consistent results were within the range 196-205 °C, therefore probably carried out at ambient pressure, and/or conditions of reduced pressure.
