I have a compounding process that releases a trace amount of 2,5-dichlorophenol CAS 583-78-8 but it has a very strong smell. I have only found an undocumented odor threshold concentration (OTC) in water.
Since the odors are a strong function of structure, and vary by orders of magnitude, I am not comfortable using the OTC in air for another dichlorophenol, unless I understand the extrapolation. Does anyone have suggestions as to where to look for OTC values of either type? (So far searched, AIHA, EPA, NIH, National Tox Prog., Sense magazine)
Is there an accepted method to predict the OTC air value from an OTC over water value?
