THE first use of the prefix ‘nor’ appears to be in a paper by Matthiessen and Foster1 published in 1868.

They had used the term ‘normal opianic acid’ to mean the completely demethylated compound, and they then used the contraction ‘methylnoropianic acid’ for the monomethyl derivative. Since that time the prefix has generally been used to… Expand
