17-(Azide-PEG9-ethylcarbamoyl)heptadecanoic t-butyl ester

17-(Azide-PEG9-ethylcarbamoyl)heptadecanoic t-butyl ester is a long-chain, azide-functionalized PEG-based click chemistry building block designed for bioorthogonal conjugation workflows. The reagent combines a hydrophobic heptadecanoate domain with a PEG9 spacer and a terminal azide handle, enabling efficient incorporation of the azide functionality into lipid-like scaffolds and polymeric or surface-bound materials. Its amphiphilic structure makes it particularly relevant for preparing clickable lipid conjugates, vesicle formulations, and imaging or assay-ready biomaterials where downstream azide–alkyne cycloaddition is used to install targeting ligands, reporter tags, or capture moieties.

1. Clickable Lipid Conjugates

17-(Azide-PEG9-ethylcarbamoyl)heptadecanoic t-butyl ester is commonly used to generate lipid-like conjugates that carry a terminal azide for subsequent copper-free or copper-catalyzed azide–alkyne cycloaddition. Researchers incorporate this reagent into hydrophobic carrier constructs to introduce a PEG spacer that improves solubility and reduces steric constraints during later conjugation steps. The resulting clickable lipid conjugates are frequently employed as modular platforms for attaching fluorescent probes, affinity handles, or bioactive surface motifs to lipid assemblies used in chemical biology and materials research.

2. Functionalized Vesicle And Membrane Tools

17-(Azide-PEG9-ethylcarbamoyl)heptadecanoic t-butyl ester supports the preparation of azide-bearing vesicles and membrane-mimetic systems by providing a long alkyl anchor coupled to a PEG9 linker. This design is well suited for building membrane surfaces that can be decorated post-assembly with alkynyl partners, allowing researchers to tune probe density and presentation without redesigning the full formulation. Such clickable vesicle tools are widely used for studying membrane interactions, creating multivalent labeling reagents, and producing standardized platforms for downstream conjugation-based assays.

3. Surface Immobilization For Diagnostics Research

17-(Azide-PEG9-ethylcarbamoyl)heptadecanoic t-butyl ester can be used to introduce azide functionality into polymeric coatings and surface-active layers where subsequent click coupling enables attachment of detection reagents. The amphiphilic heptadecanoate component facilitates incorporation into hydrophobic or lipid-compatible surface chemistries, while the PEG9 spacer helps maintain accessibility of the azide group for reliable coupling. In diagnostic reagent development and analytical chemistry workflows, this enables modular fabrication of capture surfaces, reagent cartridges, and assay components that require robust, orthogonal conjugation strategies.

4. Molecular Imaging Probe Platforms

17-(Azide-PEG9-ethylcarbamoyl)heptadecanoic t-butyl ester is frequently selected as a clickable handle for assembling imaging probe platforms that rely on late-stage installation of fluorophores, quencher units, or other reporter groups. The PEG9 linker improves the presentation of the reactive azide in heterogeneous environments such as lipid-like matrices and amphiphilic assemblies, which is advantageous when probes must remain accessible after formulation. By enabling modular azide–alkyne coupling, the reagent helps imaging-focused chemistry teams rapidly generate libraries of structurally related probe conjugates for method development and instrument-ready reagent preparation.
