Description
Fmoc-L-Cysteine-(Acetamidomethyl) is a PEPTIPURE® protected amino acid for biochemistry, supplied at a minimum purity of 99 %. It is identified by CAS number 86060-81-3, with the empirical formula C₂₁H₂₂N₂O₅S and a molar mass of 414,48 g/mol. Acetamidomethyl (Acm) protection of the cysteine thiol, together with the Fmoc α-amino group, allows orthogonal control during peptide assembly and selective later deprotection strategies. The product is This material from manufacturer Carl ROTH suits research groups that require a well-defined Fmoc-Cys(Acm) building block for solid-phase synthesis, disulfide-engineering routes and sequence construction. High minimum purity and clearly stated molecular parameters support reproducible coupling, intermediate characterisation and method transfer across organic chemistry and peptide-focused workflows where cysteine protection must remain stable under standard Fmoc conditions.

Questions about Fmoc-L-Cysteine-(Acetamidomethyl), PEPTIPURE® min. 99 %, for biochemistry, 5 g
What is this article?
Fmoc-L-Cysteine-(Acetamidomethyl), PEPTIPURE® min. 99 %, for biochemistry, 5 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Amino acids & peptides, inside Organic chemicals & synthesis reagents, in Lab chemicals.
An amino acid or a peptide is specified by the sequence or the residue, the chirality, and for a peptide the purity and the salt form. L and D forms are different compounds. A trifluoroacetate salt and a hydrochloride salt weigh differently per mole of peptide.
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?
