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:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Experimental test result conducted as per the OECD 102 test guideline.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- no
- Type of method:
- capillary method
- Melting / freezing pt.:
- > 316 °C
- Atm. press.:
- 975.6 hPa
- Decomposition:
- yes
- Decomp. temp.:
- > 316 - < 326.6 °C
- Sublimation:
- no
- Remarks on result:
- other: The test item did not melt until 316 °C, instead decomposed between 31.6.3 to 326.6 °C
- Conclusions:
- The melting point determination of test item hydrogen [4-[4-(diethylamino)-2',4' disulphonatobenzhydrylidene]cyclohexa-2,5-dien-1 ylidene]diethylammonium, sodium salt (CAS No. 129-17-9) was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The melting point was not observed till 316 oC and beyond this temperature the test item decomposed. Hence, the decomposition range was found to be 316.3°C - 326.6°C at 975.6 hPa
- Executive summary:
The melting point determination of test item hydrogen [4-[4-(diethylamino)-2',4' disulphonatobenzhydrylidene]cyclohexa-2,5-dien-1 ylidene]diethylammonium, sodium salt (CAS No. 129-17-9) was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The melting point was not observed till 316 oC and beyond this temperature the test item decomposed. Hence, the decomposition range was found to be 316.3°C - 326.6°C at 975.6 hPa
Reference
The mean decomposition range of hydrogen [4-[4-(diethylamino)-2',4' disulphonatobenzhydrylidene]cyclohexa-2,5-dien-1 ylidene] diethylammonium, sodium salt (CAS No. 129-17-9) was found to be 316.3°C - 326.6°C at 975.6 hPa.
Description of key information
