m-(4,5-dihydro-5-imino-3-methyl-1H-pyrazol-1-yl)benzenesulphonic acid

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 melts above 300°C

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:

no GLP

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Deviations:

no

GLP compliance:

no

Type of method:

thermal analysis

Key result

Decomposition:

yes

Decomp. temp.:

340 °C

Remarks on result:

other: no melting point up to decomposition

Conclusions:

The study was performed according to EU method A.1 with acceptable restrictions (no GLP) and therefore reliability of Klimisch 2 has been assigned. The substance decomposes at 340 °C without melting.

Executive summary:

The screening-DTA (closed glass crucible, heating rate 3 K/min, no GLP) of the sample Iminopyrazolsäure shows no melting point, but decomposes above about 340 °C with a heat release of about 180 kJ / kg. ‘Iminopyrazolsäure' exhibits no melting point up to 340 °C according to EC A.1.
