TCI C0439 Cyanoacetic Acid (CAS 372-09-8) combines a carboxylic acid group with an alpha nitrile, giving it a highly reactive active methylene centre. It is a standard reagent for Knoevenagel condensations and cyanoacetylation reactions in organic synthesis. The cyanoacrylic acid motif it forms is widely used as an anchoring group in dye-sensitised solar cell research, while the acid itself is a precursor to cyanoacetate esters and nitrogen heterocycles. The hygroscopic and corrosive solid should be stored tightly sealed in a cool, dry place and handled with gloves and eye protection.
