The present invention relates to kits comprising 2,4-dichlorophenoxyacetate derivatives as well as antibodies that bind to these derivatives. Inter alia, the kits can be used to label biomolecules for analytical and diagnostic applications. Some of the compounds described here can be used to label biomolecules under physiological conditions and without having to apply in situ activation. Furthermore, the presence of spacers within the 2,4-dichlorophenoxyacetate derivatives improves their binding to antibodies.

p
—[NH-A-C(O)]
n
—OH (II)
with an amino acid ester or peptide derivative of formula (III):
H—[NH-A-C(O)]
m
—O(tBu) (III)
in the presence of a coupling agent to yield a peptide compound of general formula (IV):

A series of new variants of Dde, substituted at the exocyclic alkene position have been developed and their application in solidphasepeptidesynthesis assessed. The new derivatives offer complete resistance towards 20% piperidine in DMF and provide a considerable barrier towards N→N′-intramolecular migration.
