Description
N-alpha,Nim-Bis-Boc-L-histidine N-hydroxysuccinimide ester is a protected histidine active ester with the empirical formula C₂₀H₂₈N₄O₈ and CAS number 25616-02-8. The compound has a molar mass of 452,46 g/mol. Dual Boc protection on the alpha-amino and imidazole nitrogen, combined with the N-hydroxysuccinimide ester functionality, makes this reagent suitable for controlled coupling steps where selective activation of the carboxyl group is required. Laboratories engaged in solid-phase or solution-phase peptide synthesis can use the material as a building block under standard active-ester coupling conditions. The stated molecular formula and mass support accurate stoichiometry and documentation. Offered by manufacturer Carl ROTH in its biochemicals range, this bis-Boc histidine NHS ester provides a practical option for research groups preparing protected peptide intermediates.

Questions about N-alpha,Nim-Bis-Boc-L-histidine N-hydrox, ysuccinimide ester, 1 g
What is this article?
N-alpha,Nim-Bis-Boc-L-histidine N-hydrox, ysuccinimide ester, 1 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.
