Administrative data

Endpoint:
pH
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Study period:
2002
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: pH of the aqueous solution was determined secondarily as part of a water solubility study (Method A6). The study was acceptable and well-documented and. The pH was measured at the maximal water solubility of the test substance.

Applicant's summary and conclusion

Conclusions:
The pH of an aqueous solution of the test substance was determined as part of a water solubility test. The pH of the aqueous solution was determined to be 7.27 (mean, n=3). By read-across, the pH of an aqueous solution of other alkylated naphthalene such as the study substance, should also be about 7.27.
Executive summary:

The pH of an aqueous solution of MCP 2395 was determined as part of a water solubility test. The pH of the aqueous solution was determined to be 7.27 for MCP 2395 and would be expected to be similar, by read-across (due to chemical structural similarity) for the study substance.
