- The use of secondary sources of data is acceptable when they are based on a critical evaluation of data and a consequent selection of a reliable and representative values for the properties under investigation.
The introduction to Sittig's Handbook of Toxic and Hazardous Chemicals and Carcinogens states that great care has been taken in the preparation of this work and, to the best knowledge of the Publisher and the Editors, the information contained herein is factual and accurate.
This book represents information obtained from authentic and highly regarded sources. A wide variety of references are listed. Every reasonable effort has been made to give reliable data and information. The values presented here are acceptable as they are considered to be from a reliable secondary source of phys chem. data. - GLP compliance:
- no
- Type of method:
- other: method not specified
- Remarks on result:
- not determinable
- Remarks:
- It is not possible to determine the boiling point as the substance is expected to sublime at around 100°C.
- Conclusions:
- No boiling point is available for the substance as it is expected to sublime at around 100° based on data taken from a peer reviewed handbook.

- The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative values for the properties under investigation.
The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are considered to be from a reliable secondary source of phys chem. data. - GLP compliance:
- no
- Type of method:
- other: unknown method
- Remarks on result:
- not determinable
- Remarks:
- It is not possible to determine the boiling point as the substance is expected to sublime.
- Conclusions:
- No boiling point is available for the substance as it is expected to sublime based on data taken from a peer reviewed handbook.

- Data detailed in the International Chemical Safety Card (ICSC) for 1,4-Naphthoquinone. These cards are meant as a way of summarising essential information on chemical substances; and were jointly developed by the IPCS and the European Commission.
The cards are then peer-reviewed by a committee consisting of internationally-recognized experts who take into account advice given by manufacturers, workers' representatives and poisons centres.
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative values for the properties under investigation.
Based on the above information, although full experimental details are unknown, the values presented here are acceptable as they are considered to be from a reliable secondary source of phys chem. data. - GLP compliance:

Description of key information
Reliable handbook and secondary source information is available indicating that the substance sublimes starting at around 100°C. Accordingly it is not possible to determine a boiling point for the substance as such.
Key value for chemical safety assessment
