Full Title

Compounds containing amino and etherified hydroxy groups bound to the same carbon skeleton > having etherified hydroxy groups and amino groups bound to acyclic carbon atoms of the same carbon skeleton > the carbon skeleton being acyclic and saturated > having one amino group and at least two singly-bound oxygen atoms, with at least one being part of an etherified hydroxy group, bound to the carbon skeleton, e.g. ethers of polyhydroxy amines > having the oxygen atom of at least one of the etherified hydroxy groups further bound to a carbon atom of a six-membered aromatic ring > the six-membered aromatic ring being part of a condensed ring system containing rings other than six-membered aromatic rings
