1-(2-hydroxy-3-sulphonatopropyl)pyridinium

Boiling point

Administrative data

Endpoint:

boiling point

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is a solid which decomposes before boiling

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

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:

guideline study with acceptable restrictions

Remarks:

non-GLP

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Version / remarks:

27th July 1995

Deviations:

no

GLP compliance:

no

Type of method:

capillary method

Key result

Melting / freezing pt.:

245.4 °C

Decomposition:

yes

Decomp. temp.:

ca. 245.4 °C

Remarks on result:

other: result is mean value of two determinations; no information on atm. pressure given

Conclusions:

The study was performed according to OECD TG102 without deviations and therefore reliability of Klimisch 2 has been assigned. The test material melted at 245.4 °C under degradation.

Executive summary:

The melting point of the test substance was determined experimentally using the capillary method in a non-GLP test according to OECD guideline 102. A preliminary test and 2 measurements in the main test have been conducted. The test material melted at 245.4 °C under degradation.
