Description General description N,N,N′,N′-Tetramethyl-O-(N-succinimidyl)uronium tetrafluoroborate is commonly used for the conversion of carboxylic acid into the corresponding N-hydroxysuccinimidyl (NHS) ester. Application N,N,N′,N′-Tetramethyl-O-(N-succinimidyl)uronium tetrafluoroborate may be used in the synthesis of N-succinimidyl 4-[18F]fluorobenzoate ([18F]SFB), a 18F-labeled agent used for labeling biomarkers. it may also be used for the activation of carboxylic group of C16-chained alkanethiols that are used in developing surface plasmon resonance (SPR) sensors.
