A labeling reagent for use in oligonucleotide ("oligo") synthesis, as well as a method of preparing such a labeling reagent, a method of using such a reagent for synthesizing a labeled oligonucleotide, and an oligonucleotide prepared using such a reagent. The reagent can be used to label either the 3' or 5' termini of a synthesized oligo, and/or for one or more positions along the oligo. The labeling reagent can be prepared by a reaction scheme that involves the initial preparation of hydroxyacids, tritylated hydroxyacids and coupling of such derivatives to diamine, wherein the amine function serves at an attachment point for labels and the hydroxyl groups can either be used to immoblize the molecules to support or can be converted to provide a phosphorylating reagent.
