Product Profile
Chondroitin Sulfate Sodium CPC 90%
Core identity and supply information for the documented chondroitin sulfate powder grade.
Grade Characteristics
What Defines This Chondroitin Sulfate Powder Grade
The CPC 90% designation, sodium salt form and physical powder characteristics distinguish this material from other chondroitin grades used in commercial formulations.
CPC 90% Grade
The product is specified as Chondroitin Sulfate Sodium CPC 90%. This grade should be distinguished from higher-content chondroitin materials when matching an existing formula or purchasing specification.
USP-Based Testing
The documented specification uses USP methods across identity, content, purity, microbiological and several physical quality parameters.
Powder Characteristics
Particle size and density are relevant to powder handling and manufacturing behavior, particularly for blending and solid-dose production.
