Reference
Endpoint:
water solubility
Type of information:
other: data from safety datasheet
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Company data such as SDS can be assessed as data source reliable with restrictions, thus a Klimisch 2 rating was given.
Qualifier:
according to guideline
Guideline:

other: no data
Water solubility:
>= 500 000 mg/L
Temp.:
20 °C
pH:
8
Remarks on result:
other: The preparation IMEXINE OD contains toluene 2,5 diamine in 50% aqueous solution, which gives evidence on the high water solubility of target chemical toluene-2,5-diamine (CAS 95-70-5).
Details on results:
IMEXINE OD is an industrial preparation used in manufacturing processes. This preparation contains target chemical toluene 2,5 diamine in 50% aqueous solution, what provides evidence on the high water solubility >= 500000 mg/L of target chemical toluene-2,5-diamine (CAS 95-70-5).Furthermore, according to the MSDS, the preparation IMEXINE OD, i.e. toluene 2,5 diamine in 50% aqueous solution, is "100 % soluble (w/w)" in water.
Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L) "100 % soluble (w/w)"IMEXINE OD is an industrial preparation which contains target chemical toluene 2,5 diamine (CAS 95-70-5) in 50% aqueous solution, providing evidence on the high water solubility >= 500000 mg/L of toluene-2,5-diamine.
Executive summary:

Company data of CHiMEX are provided by a SDS on IMEXINE OD. IMEXINE OD is an industrial preparation used in manufacturing processes. This preparation contains target chemical toluene 2,5 diamine (CAS 95 -70 -5) in 50% aqueous solution, providing evidence on the high water solubility >= 500000 mg/L of toluene-2,5-diamine. Furthermore, according to the SDS, the preparation IMEXINE OD, i.e. toluene 2,5 diamine in 50% aqueous solution, is "100 % soluble (w/w)" in water.

Description of key information

The test substance 2-methyl-p-phenylenediamine (CAS 95-70-5) is highly soluble in water, based on company data >= 500000 mg/L.

Key value for chemical safety assessment

Water solubility:
500 000 mg/L
at the temperature of:
20 °C

Additional information

A weight of evidence approach is being applied. Two chemistry handbooks indicate that target chemical 2-methyl-p-phenylenediamine (CAS 95-70-5) is "soluble" in water, or "highly soluble", respectively. Company data provided by a MSDS on preparation IMEXINE OD, which contains 2-methyl-p-phenylenediamine in 50% aqueous solution, provides evidence that the water solubilty in fact is >= 500000 mg/L.
