Terminal Modifiers Phosphoramidites
Spacer, amino, thiol, phosphorylation and other linker phosphoramidites for oligonucleotide conjugation. Confirm the exact identity, supplied form, specification, package and current availability on the product page or by inquiry.
Category guide
Linker Phosphoramidites products provide protected, sequence-addressable building blocks for solid-phase oligonucleotide synthesis and modified-sequence research.
Confirm base and sugar identity, protecting groups, stereochemistry, linker or label position, and compatibility with coupling and deprotection conditions.
Review identity, chromatographic purity, phosphorus-related quality attributes, water sensitivity and performance in a short test sequence.
Product-family considerations
- 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.
- 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.
Selection checklist
| Exact identity | Match the canonical name with a CAS number, structure, SMILES or drawing; confirm stereochemistry, protecting groups and salt form where applicable. |
|---|---|
| Specification | Define target purity, analytical method, water or residual-solvent concerns and application-specific acceptance limits. |
| Workflow fit | Share the reaction, enzyme, sequence, solvent system, support or analytical method used to evaluate compatibility. |
| Supply need | Provide initial quantity, expected future scale, packaging preference, timeline and documentation requirements. |
