Acrylamide CAS#79-06-1
Acrylamide is a significant organic monomer with extensive applications in synthetic chemistry. It offers both strong chemical reactivity and distinctive physical properties. At ambient temperature, it presents as a white crystalline solid. While the pure form is odorless, industrial-grade material may show a slight yellowish coloration or a mild sharp smell, attributable to minor impurities. The crystals are hygroscopic, readily taking up atmospheric moisture, which can cause them to progressively soften or eventually dissolve.
