0.25 M Hyacinth BMT Solution (BMT in anhydrous acetonitrile)

Hyacinth BMT activator (also known as 5-Benzylmercapto-1H-tetrazole or BTT) demonstrates important advantages in the syntheses of oligonucleotides: • Coupling efficiencies of 99% with impeccable quality

• Lower percentage of n-1 sequences
• Dramatic reduction of coupling times to under 3 minutes in RNA syntheses
• Efficient RNA synthesis using 50% or less TBDMS, TOM® or ACE® monomer
• Excellent batch to batch consistency for reproducible and stable oligo production

Application Note

Hyacinth BMT Solution (5-Benzylmercapto-1H-tetrazole in anhydrous acetonitrile) is a chemical activator for RNA and DNA synthesis and is used as a substitute for 1H-Tetrazole, DCI and ETT. In case of RNA synthesis it is compatible with both TBDMS and TOM protected monomers. It improves RNA coupling yields to 99%, requires only 3 minutes coupling times, requires 50% less phosphoramidite for each coupling and is easy to handle.
