Acrylamide
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH2=CHC(O)NH2. It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH2). It is produced industrially mainly as a precursor to polyacrylamides, which find many uses as water-soluble thickeners and flocculation agents.

Acrylamide forms in burnt areas of food, particularly starchy foods like potatoes, when cooked with high heat, above 120 °C (248 °F). Despite health scares following its discovery in 2002, and its possible classification as a carcinogen, acrylamide from diet is thought unlikely to cause cancer in humans; Cancer Research UK categorized the idea that burnt food causes cancer as a "myth".
