EC number: 243-072-0
CAS number: 19438-60-9
NOEC: 11 mg/L
No aquatic toxicity studies with chronic exposure are available on the
registered substance itself. Reliable data on fish are available for two
structural analogues of the substance, MTHPA and phthalic anhydride,
with determined NOEC values of 100 and 10 mg/L, respectively. The lower
NOEC value of 10 mg/L determined for phthalic anhydride was used as
suitable read-across value for 4-MHHPA considering a worst case
approach. The NOEC from this study was 10 mg/L which, when corrected for
differences in molecular weight, results in a calculated NOEC of 11 mg/L
for 4 -MHHPA.
