Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- < -80 °C
- Remarks on result:
- other: the substance was still liquid at -80°C
Applicant's summary and conclusion
- Conclusions:
- In a pre-test, the test item ISOPROPYL NITRITE was still unfrozen and liquid at – 80 °C.
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation the determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C. Therefore, no additional test was conducted and the freezing point is stated as: < - 80 °C (< 193.15 K).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
