Stereodefined PS Phosphoramidites
Stereocontrolled phosphorothioate synthesis reagents and activators, including PSI-ψ- and CMPT-type chemistry, for research-use oligonucleotide method development. Confirm the exact identity, supplied form, specification, package and current availability on the product page or by inquiry.
Category guide
Stereopure PS reagents and activators support research into stereodefined phosphorothioate linkage formation and route evaluation in oligonucleotide synthesis.
Confirm the reagent family, target backbone configuration, compatible activation and coupling conditions, solvent system, monomer set and sequence context.
Confirm identity, assay and stereochemical specification; control moisture and solution age; then verify conversion and stereochemical outcome on representative sequences.
Product-family considerations
- Provides a dedicated category for PSI-ψ- and CMPT-type research workflows instead of mixing stereocontrolled PS chemistry with general sulfurizing reagents.
- Supports method comparison around reagent family, activation conditions, sequence context and target phosphorothioate configuration.
- Performance and stereochemical outcome are workflow-specific and require validation with the intended monomers, sequence, solvent system and synthesis platform.
- Research-use material and method information do not replace product-specific specifications, handling controls or user qualification.
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. |
