Category guide

Typical use

Linker Phosphoramidites products provide protected, sequence-addressable building blocks for solid-phase oligonucleotide synthesis and modified-sequence research.

How to select

Confirm base and sugar identity, protecting groups, stereochemistry, linker or label position, and compatibility with coupling and deprotection conditions.

How to qualify

Review identity, chromatographic purity, phosphorus-related quality attributes, water sensitivity and performance in a short test sequence.

Product-family considerations

Common advantages
  • Phosphoramidite chemistry is modular, automated and compatible with fast sequence iteration.
  • Modified sugar, base or linker motifs let researchers tune duplex stability, specificity, hydrophobicity, steric profile and downstream conjugation options.
Common limitations
  • Modified amidites can require adjusted coupling time, activator choice, deprotection conditions and analytical release methods.
  • Moisture sensitivity and storage history are important because degraded amidite can reduce coupling efficiency.
