NovaBioX® Croscarmellose Sodium CAS 74811-65-7
（Superdisintegrant Excipient）
Chemical Name: Croscarmellose Sodium
CAS No.: 74811-65-7
Croscarmellose Sodium is a internally cross-linked sodium carboxymethylcellulose, serving as a disintegrant in pharmaceutical formulations. It appears as a white or off-white, free-flowing powder with high purity and excellent water absorption. Its cross-linked network structure prevents gel layer formation, enabling rapid wicking and swelling. This unique swelling action generates sufficient hydrodynamic pressure to rupture tablets or capsules, promoting fast drug release.
