Precursor ion
precursor ion

progenitor ion

Deprecated: parent ion.

Ion that reacts to form particular product ions or undergoes specified neutral losses. The reaction can be of different types including unimolecular dissociation, ion/molecule reaction, change in charge state, possibly preceded by isomerization.

Precursor ion

Synonymous with parent ion. Instead of the use of parent ion and daughter ion terms the precursor and product ion terms are preferred respectively.

Daughter ion and related terms

QUOTED TEXT FROM IUPAC RECOMMENDATIONS 2013
The anthropomorphic terms for ions involved in fragmentation reactions, for example, “daughter ion”, have fallen into disuse after strong sentiments against the use of the term were voiced two decades ago [1][2]. The term product ion is recommended in place of daughter ion and precursor ion in place of parent ion. The use of nth-generation product ion is recommended in place of granddaughter ion and similar terms.
