Acrylamide CAS#1979-6-1
Excellent Chemical Reactivity – Serves as an important organic synthesis monomer with versatile chemical reactivity.
White Crystalline Appearance – Pure acrylamide is a white crystalline powder at room temperature, offering a consistent physical form.
Odorless Pure Product – High-purity acrylamide is odorless, making it distinguishable from industrial-grade products containing trace impurities.
Moisture Absorption Capability – Exhibits hygroscopic properties, allowing it to absorb moisture and gradually soften or dissolve.
Acrylamide is an important monomer used in organic synthesis, characterized by its chemical reactivity and distinctive physical properties. Under normal room-temperature conditions, it appears as a white crystalline powder. Pure acrylamide is odorless, whereas industrial-grade products may exhibit a slightly yellowish color or a pungent odor due to trace impurities. Its crystalline form is hygroscopic, readily absorbing moisture from the environment and gradually softening or even dissolving as moisture content increases.
