N4,N4'-dipheny-N4,N4'-bis(9-phenyl-9H-carbazol-3-yl)biphenyl-4,4'-diaMine Usage And Synthesis

Chemical Properties

Pale yellow solid powder

Uses

Cap 1 is suitable for use after the phosphoramidite reaction/coupling step.

Biological Activity

Cap 1 solution aborts chains bearing unreacted 5μhydroxyl groups due to failure of reaction with activated phosphoramidite (typically, 1 to 2% of growing oligonucleotide chains in each synthesis cycle). These unreacted 5μhydroxyl groups are capped with an acetyl group and thus rendered unreactive for subsequent synthesis steps.
