General description

1-Cyano-4-dimethylaminopyridinium tetrafluoroborate is an organic cyanylating agent also termed CDAP. It is a unique cystine-labeling reagent due to its reactive nature under acidic conditions. This feature provides CDAP an advantage over other sulfhydryl labeling agents, as it can avoid potential thiol-disulfide exchange.
We are committed to bringingyou greener alternative products, which adhere to one or more of the 12Principles of Greener Chemistry. 1-Cyano-4-DimethylaminopyridineTetrafluoroborate (CDAP) is a safer alternative to cyanogen bromide (CNBr) foractivating soluble polysaccharides in vaccine development. It operates at lowerpH levels, reducing toxicity and side reactions. CDAP enables quick activationfor protein-polysaccharide conjugate vaccines, bioconjugation, and drugdelivery, promoting sustainable practices in biochemistry and pharmaceuticals.

Application

1-Cyano-4-dimethylaminopyridinium (CDAP) has been used in the synthesis of conjugate vaccines as a cyanylating agent. Activation of cellulose dialysis membrane for immunosensor applications used CDAP as an activation agent.

Features and Benefits

When compared to Cyanogen Bromide (CNBr), a similar reagent, CDAP is:

  • Easier to use.
  • Can operate at lower pH levels.
  • Fewer side reactions.
  • Cyanogen Bromide is hazardous in nature.
