Description
Fmoc-PEG3-NHS ester is a PEGylation building block offered at a minimum purity of 95 % for biochemical conjugation and linker chemistry. With CAS number 1352827-47-4 and the empirical formula C₂₈H₃₂N₂O₉, the molecule presents an Fmoc-protected amine, a short PEG3 spacer and an N-hydroxysuccinimide ester for coupling to primary amines. It has a molar mass of 540,6 g/mol and a density of 1,33 g/cm³, supporting accurate stoichiometric work in peptide modification, surface functionalisation and bioconjugate synthesis. Laboratories can integrate it into established conjugation protocols used in medicinal chemistry and life-science research, benefiting from clear CAS, formula and molar-mass data for documentation and reproducible experimental design across exploratory and routine workflows.

Questions about Fmoc-PEG3-NHS ester, min. 95 %, 50 mg
What is this article?
Fmoc-PEG3-NHS ester, min. 95 %, 50 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Milieux microbiologiques.
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.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
