Modified Nucleotides
5-Aminopropargyl UTP Tetrasodium Salt
Quick view. A 5-aminopropargyl-modified UTP building block supplied in tetrasodium form for research-use nucleic-acid synthesis and enzymatic RNA incorporation studies. Exact-form composition and the current specification are confirmed by inquiry. A public CAS number is not assigned for this exact form. Catalog target purity: By inquiry. Availability: Inquiry only — contact BX Lab to confirm current availability.
Identifier context
These notes preserve the current catalog identifiers while making their review boundary explicit.
The retained free-acid identifier is not published as the identifier of the complete tetrasodium catalog product.
Tetrasodium and related free-acid formula and molecular-weight values are withheld until the complete supplied form is independently bound.
The catalog-default purity is not published because it is not a current BX Lab specification and conflicts with the retained supplier page. Confirm the current analytical specification by inquiry.
Product profile
5-Aminopropargyl UTP Tetrasodium Salt is classified as modified nucleotides.
5-Aminopropargyl UTP Tetrasodium Salt — Modified UTP building block for research-use nucleic-acid synthesis and enzymatic RNA incorporation studies.
For 5-Aminopropargyl UTP Tetrasodium Salt, copper-catalyzed, copper-free or inverse-electron-demand click conditions can affect sensitive oligonucleotides differently; residual metal, solvent and purification strategy should be controlled.

Product-specific evaluation notes
Potential advantages
- Click-compatible handles separate oligonucleotide synthesis from late-stage labeling, which helps screen multiple payloads from a common intermediate.
- Reactive handles make the product adaptable across dye-labeling, surface-coupling and ligand-conjugation workflows.
Method limitations
- Copper-catalyzed, copper-free or inverse-electron-demand click conditions can affect sensitive oligonucleotides differently; residual metal, solvent and purification strategy should be controlled.
- Functional handles may require orthogonal protection, pH control and rapid purification to avoid hydrolysis, oxidation or cross-reaction.
