Morphology
The phrase is compositionally built: it denotes a 'radical' that is of or derived from 'cyanide' (i.e. a reactive -CN species). If a B1 learner knows 'cyanide' (a cyanide compound) and 'radical' (a highly reactive chemical species), they can infer it refers to a reactive cyanide species, so the meaning is directly derivable from the parts.
Etymology
Cyanide radical comes from old chemistry words: cyanide came from a word for 'dark blue' because early chemists saw a blue dye, and radical once meant 'root' or a small 'group' of atoms. So the name points to the little atomic 'root' -CN that acts as one piece inside many chemicals, which is why we use the term for that chemical group.
