Microcrystalline Cellulose (CAS 9004-34-6), commonly abbreviated as MCC, is a purified, partially depolymerized cellulose derived from fibrous plant material. Functioning as a non-reactive binder, diluent, and disintegration aid, this white, free-flowing powder is the gold standard excipient in the formulation of solid dosage forms. It is extensively utilized in pharmaceutical direct compression tableting, capsule filling, and as an anti-caking agent in industrial food processing. We provide this industrial material with competitive factory pricing to support continuous manufacturing operations, alongside options for customized specifications (such as particle size and bulk density). Essential technical documentation, including MSDS, TDS, COA, is readily available for all bulk supply orders.

FAQ - Technical & Supply Chain
-
Q:
What distinguishes Microcrystalline Cellulose under CAS 9004-34-6 from standard fibrous cellulose?
A: While CAS 9004-34-6 applies to cellulose generally, Microcrystalline Cellulose distinguishes itself as a depolymerized, acid-hydrolyzed grade with removed amorphous regions, specifically processed for compressibility rather than fibrous reinforcement. -
Q:
Is this grade suitable for direct compression tableting?
A: Yes, this material is typically characterized by excellent compressibility and flow properties, making it intended for use as a primary binder in direct compression manufacturing.
