- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- Since the test item is a reaction mass of hexadecanoic anhydride and hexadecanoic acid, hexadecanoic anhydride was used for the read-across.

Description of key information
The melting point of the test item reaction mass of hexadecanoic anhydride and hexadecanoic
acid was calculated based on read-across to hexadecanoic anhydride and hexadecanoic acid.Calculation for melting point with software tool MPBPWIN v1.43 for hexadecanoic anhydride: 64 °C
Calculation for melting point with software tool MPBPWIN v1.43 for hexadecanoic acid: 61.8 °C
The melting point for the test item reaction mass of hexadecanoic anhydride and hexadecanoic acid could be included between these values, therofore circa 62.9 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 62.9 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
