A mass label for labelling and detecting a biological molecule by mass spectroscopy, which label comprises the following structure: X-L-M wherein X is a mass marker moiety comprising the following group: formula (I), wherein the cyclic unit is aromatic or aliphatic and comprises from 0-3 double bonds independently between any two adjacent atoms; each Z is independently N, N(R ), C(R ), CO, CO(R ), C(R )2, O or S; X is N, C or C(R ); each R is independently H, a substituted or unsubstituted straight or branched C1-C6 alkyl group, a substituted or unsubstituted aliphatic cyclic group, a substituted or unsubstituted aromatic group or a substituted or unsubstituted heterocyclic group; and y is an integer from 0-10, L is a cleavable linker comprising an amide bond and M is a mass normalization moiety.
