HyNic NHS ester

HyNic NHS ester is a heterobifunctional linker molecule. It contains an amine-reactive N-hydroxysuccinimide (NHS) moiety and a hydrazine moiety that reacts with the aldehyde functional group in SFB (succinimidyl 4-formylbenzoate, Item No. 30477) to form a bis-aryl hydrazone linker that is quantifiable spectrophotometrically at 354 nm. HyNic NHS ester has been used in the formation of small molecule-antibody, polymer-enzyme, protein-liposome, and peptide-peptide conjugates.. SMILES: O=C(C1=CN=C(N/N=C(C)\C)C=C1)ON2C(CCC2=O)=O. InChi Code: InChI=1S/C13H14N4O4/c1-8(2)15-16-10-4-3-9(7-14-10)13(20)21-17-11(18)5-6-12(17)19/h3-4,7H,5-6H2,1-2H3,(H,14,16). InChi Key: PRZHEFYNLJWJFA-UHFFFAOYSA-N
