Description
DBCO-PEG4-NHS ester is a bifunctional bioconjugation reagent with a minimum purity of 95 %, CAS number 1427004-19-0 and empirical formula C₃₄H₂₉N₃O₁₀. Its molar mass of 649,7 g/mol corresponds to a structure that combines a dibenzocyclooctyne (DBCO) moiety for strain-promoted azide–alkyne cycloaddition with an N-hydroxysuccinimide ester for amine-reactive coupling, connected by a PEG4 spacer. Chemical biology, diagnostics and materials research groups can use this linker when preparing DBCO-functionalized conjugates for subsequent azide coupling. The product is available from manufacturer baseclick and supports reproducible multi-step labeling workflows that require mild reaction conditions and defined NHS reactivity. The compact pack size is practical for method development, titration and small-batch conjugations. Applied according to standard laboratory practice, DBCO-PEG4-NHS ester provides a well-specified building block for demanding bioconjugation and probe-assembly applications.

Questions about DBCO-PEG4-NHS ester, min. 95 %, 5 mg, plastic
What is this article?
DBCO-PEG4-NHS ester, min. 95 %, 5 mg, plastic is the article on this page. Luminix Health distributes baseclick for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
Which category should I open next?
