High-end pharmaceutical raw materials and excipients

Pharmaceutical excipients are excipients and additives used in pharmaceutical production and in prescriptions preparation; Other than active ingredients, pharmaceutical excipients are substance that have been reasonably assessed for safety and contained in pharmaceutical preparation. Pharmaceutical excipients are important ingredients that may affect quality, safety and efficacy of pharmaceutical products. In addition to shaping, acting as a carrier and improving stability, they have more important functions such as solubilization, latent solvent, slow and controlled release.
API, refers to active pharmaceutical ingredients that are raw material drugs used in preparations production. Prepared by chemical synthesis, plant extraction, or biotechnology, they are powders, crystals, extracts, etc. that are used for medicinal purposes, which cannot be directly administered by patient.

Microcrystalline cellulose

Name	Contents
Chemical Name	Microcrystalline cellulose
CAS No	9004-34-6
Definition	The main composition of microcrystalline cellulose (MCC) is β-1,4-glucoside bonded straight chain polysaccharides. MCC is a white, odorless and tasteless crystalline powder that is produced by acid hydrolysis of wood pulp or cotton linter to the levelling off degree of polymerization (LODP).
Main Application	MCC is commonly used as an adsorbent, suspension agent, diluent or disintegrant. MCC is widely used as thinners and adhesives in pharmaceutical tablets including oral tablets and capsules, and can be used not only for wet granulation but also for dry direct tablet pressing.

Betadex Sulfobutyl Ether Sodium

Name	Contents
Chemical name	CDE：Sulfobutyl ether-β-cyclodextrin sodium USP：Betadex Sulfobutyl Ether Sodium EP：Sulfobutylbetadex sodium
CAS Number	182410-00-0
Definition	Betadex Sulfobutyl Ether Sodium is prepared by alkylation of betadex using 1,4-butane sultone under basic conditions. The average degree of substitution in betadex is strictly controlled between 6.2 and 6.9.
Advantages	Betadex sulfobutyl ether sodium is a new type of anionic high water-soluble cyclodextrin derivatives. It could not only include drug molecules to form covalent compounds so that increase the drug's stability, solubility, safety, and also reduce the renal toxicity, moderate drug's hemolysis, control the release rate and cover up the bad smell.
Main Application	Betadex sulfobutyl ether sodium is used as a solubilizer, stabilizer, wetting agent, chelating agent (complexing agent) and polyvatent masking agent in injection, oral, nasal and eye medicines.
