    Abstract: A silyloxy aromatic derivative capable of alkylating a target biological molecule when activated by ionic strength. A sequence directed reagent may be constructed by conjugating a methyl silyloxy aromatic derivative to a hexamethyiamino linker attached to either the 5' or 3' terminus of an oligonucleotide. Annealing this modified fragment of DNA to its complementary sequence allows for target modification subsequent to ionic activation. The product of this reaction is a covalent crosslink between the reagent and target strands resulting from an alkylation of DNA by the activated silyloxy aromatic derivative. In a preferred embodiment, a nitrophenyl or bromo group is attached to a methyl group of the silyloxy aromatic derivative. This reagent may be similarly linked to an oligonucleotide probe. Activation of the alkylating agent by an ionic signal (X) which may naturally occur, or may be introduced into the media containing the target molecule, such as by the introduction of a salt (MX).
