water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
from 2001-01-22 to 2001-01-25
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: See 'Remarks'
Non-GLP study, similar to the flask method (OECD 105 or EEC A6), some deviations do not allow full validation: no pH reported, analytical method based on DOC. Therefore, the study is considered as reliable with restrictions.
according to guideline
other: DIN 38409 Part 3
equivalent or similar to guideline
OECD Guideline 105 (Water Solubility)
Principles of method if other than guideline:
The water solubility of dimetol was determined in a screening test via DOC-Analysis according to a method of Fa. Bayer AG.
GLP compliance:
Type of method:
other: analysis of dissolved organic carbon
Specific details on test material used for the study:
Commercial name :FREESIOL / CORPS 119 (as reported in the report)

Chemical nature : 2-heptanol, 2,6-dimethyl-
Empirical formula : C9H20O
Molecular weight : 144.2 g/mol
CAS number : 13254-34-7
EC number : 236-244-1
batch : 50652410
purity: 99.5 %
Density : 0.817 g/cm3 at 20°C
Expiry date : 2001-11-30
Recommended storage : cool, protected from moisture
Storage at Testing Facility Refrigerator 7+/- 2°C, protected from light and moisture
Water solubility:
745 mg/L
20 °C

DOC-Analysis after 24h and 72h Test duration:

24h 72h
Test item [mg/L] Content of carbon [mg/L](1) DOC [mg/L] Test item [mg/L] DOC [mg/L] Test item [mg/L]
1000 746 568.35 758 548.78 732
Solubility of test item [mg/L] (Mean value) 745

DOC-values of test item were corrected by values of control

(1) = content of carbon takes into account the purity of test item

The water solubility of the test substance is 745 mg/L at 20°C.
Executive summary:

The water solubility of Dimetol was measured via analysis of dissolved organic carbon (DOC), according to DIN 38409 Part 3. Results at 24 and 72h were considered to be constant, so the mean value was retained.
