“…The synthesis and characterization (IR, 1 H NMR, UV-Vis and thermogravimetry, derivative thermogravimetry, TG -DTG) of the Schiff bases of DDS and o-, m-, p-hydroxybenzaldehydes (o-, m-, p-HB), i.e., o-HB -DDS, m-HB -DDS, and p-HB -DDS; the corresponding formaldehyde-condensed resins, i.e., o-HB -DDS -HCHO, m-HB -DDS -HCHO, and p-HB -DDS -HCHO along with their corresponding Cu 2+ and Ni 2+ polychelates have been reported previously (16).…”

“…It has been derivatized with propargylamine to yield building blocks for the production of dendrimers, which are a new group of strong antioxidant compounds . Like ortho and meta hydroxybenzaldehydes, this isomer is also involved in the synthesis of aldehyde methacrylates , and chelating resins. , …”
