Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Melting / freezing pt.:
- 38 °C
- Atm. press.:
- 1 013.3 hPa
- Conclusions:
- A melting point of 38°C was determined for 2-chloro-5-chloromethylpyridine.
- Executive summary:
A study was conducted to assess the melting point of 2 -chloro-5-chloromethylpyridine accronding to EU test method A.1 which is equivaled to OECD 102 by differential scanning calorimetry. The test item was heated up from ambient temperature to the final temperature (300 °C) at a constant heating rate (10 K/min) in a defined atmosphere (nitrogen). The quantity of heat absorbed or released was measured and recorded. Aluminium crucibles with a small hole were used as containers for the test item and as empty reference crucible. A melting point of 38°C was determined for 2 -chloro-5-chloromethylpyridine.

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.
