- Key result
- Melting / freezing pt.:
- ca. -28 °C
- Remarks on result:
- other: Extrapolated onset temperature
- Conclusions:
- An extrapolated onset temperature (i.e. melting point) of -28 °C was obtained for Reaction mass of morpholine and 6-[(p-tosyl)amino]hexanoic acid, compound with morpholine (1:1) following heating of the test material by differential scanning calorimetry
- Executive summary:
The melting point of Reaction mass of morpholine and 6-[(p-tosyl)amino]hexanoic acid, compound with morpholine (1:1) was determined using differential scanning calorimetry, a thermosanalytical technique, in accordance with OECD Guideline 102 (Melting point / Melting Range). The extrapolated onset temperature of the melting of the substance was reported to be -28°C, although the broad nature of the melting endotherm suggested that the sample would melt over a temperature range. There was good correlation between either experimental run.
Reference
The extrapolated onset temperature was reported as -28°C, although the broad nature of the melting endotherm indicated that Reaction mass of morpholine and 6-[(p-tosyl)amino]hexanoic acid, compound with morpholine (1:1) melts over a temperature range. The results of the two experimental runs were in close agreement.
Description of key information
The extrapolated onset temperature of the melting of the substance was reported to be -28°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -28 °C
Additional information
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.
