We Didn’t Know About It Yesterday!
We have added the hazard alert about the peroxidizable character of some
alcohols, such as 2-octanol, to our chemical listings. This development may
not be new; however, one of the many benefits of the Flinn Scientific Catalog/
Reference Manual is that it keeps science teachers up-to-date.
