A solid support for oligonucleotide synthesis has the structure <IMAGE> where CPG represents a controlled pore glass matrix, the wavy line represents a carbon chain covalently linking the NH group with the controlled pore glass matrix, X is 2,2'-dimethoxytrityl or H, and R is alkyl, aryl, arylalkyl, heteroalkyl, or heteroaryl. The dimethoxytrityl group is removed from the solid support by treatment with acid, and the oligonucleotide is built, step-by-step in a conventional synthesizer after attachment of the 3' end of the first oligonucleotide unit to the hydroxyl function connected to the R group.
