Used in solid-phase oligonucleotide synthesis, this phosphoramidite reagent enables the incorporation of a dimethoxytrityl-protected deoxyadenosine derivative with a benzoyl base protection. It is essential for automated DNA synthesis, particularly in the preparation of custom sequences for PCR primers, probes, and gene fragments. The DMT group allows for efficient monitoring of coupling success through colorimetric detection during synthesis, while the phosphoramidite functionality ensures high coupling efficiency. Commonly applied in research, diagnostics, and drug development where precise DNA constructs are required.
