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.
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.
