Application

N-Hydroxysuccinimide can be used in the synthesis of N-hydroxysuccinimide ester via dehydration reaction in the presence of dicyclohexylcarbodiimide in carboxylic acid.
N-Hydroxysuccinimide has been used in the synthesis of intermediates such as:
  • N

  • -succinimidyl 3-(di-tert-butylfluorosilyl)benzoate
  • 4-[2,2-bis[(p-tolylsulfonyl)-methyl] acetyl]benzoic acid-NHS ester
  • N-succinimidyl 3-iodobenzoate

It has also been used in a protocol for the surface modification of microchannels of a microfluidic-integrated surface plasmon resonance (SPR) platform for the detection and quantification of bacterial pathogens.
Additive used in the carbodiimide method for improved amidations and peptide couplings.
