Batch number: 55503625
Purity: 100%
Expiry date: 28 April 2019
Date received: 28 April 2017 - Key result
- Boiling pt.:
- < 300 °C
- Atm. press.:
- 1 021 mBar
- Remarks on result:
- not determinable
- Conclusions:
- The boiling temperature of DNAN was not determinable as it decomposed at temperatures above approximately 300°C before boiling.
- Executive summary:
A study was performed to determine some physicochemical properties of the test item, DNAN. The methods followed are amongst those described in Commission Regulation (EC) No. 440/2008 and the OECD Guidelines for the Testing of Chemicals. The physicochemical properties which have been determined in this study are detailed below, together with the result obtained for each test.
EC OECD Test Result
method no. method no.
A.1 102 Melting temperature 88 to 96°C
A.2 103 Boiling temperature Not determinable; decomposes from approximately 300°C before boiling
A.3 109 Relative density 1.53

Description of key information
The boiling temperature of DNAN was not determinable as the test item decomposed at temperatures above approximately 300°C before boiling.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 300 °C
Additional information
Boiling point determination was conducted as a package of physicochemical testing on DNAN (Envigo CRS Limited, NC15WS, 2018). The study was performed according to EC Method A.2 and OECD Method 103 and in compliance with GLP. The boiling temperature was examined by differential scanning calorimetry (DSC).
The boiling temperature of DNAN was not determinable as the test item decomposed at temperatures above approximately 300°C before boiling.
For assessment the boiling point of 300°C is taken as a worst case.
