Description
Z-L-pyroglutamic acid N-hydroxysuccinimide ester is an activated amino-acid derivative with CAS number 40291-26-7 and empirical formula C₁₇H₁₆N₂O₇. Its molar mass of 360,32 g/mol supports precise stoichiometric planning in peptide coupling and related conjugation chemistry. The product is supplied as the N-hydroxysuccinimide ester Available from manufacturer Carl ROTH, this biochemical fits chemical and biochemical catalogues and new-product highlight selections where protected pyroglutamic building blocks are needed. The Z-protected pyroglutamic NHS ester structure is suited to amide-bond formation under controlled laboratory conditions and to workflows that document CAS identity, formula and molar mass for traceability. Researchers working on peptide intermediates, activated esters or related organic transformations can integrate into routine ordering without relying on undersized research aliquots. Clear specification data help align the material with standard laboratory documentation practices.
