Sodium chondroitin sulfate

Sodium chondroitin sulfate (CAS 9082-07-9) is a sulfated glycosaminoglycan derived primarily from bovine, porcine, or marine cartilage sources. Commercially recognized as chondroitin sulfate sodium salt, it functions as a structural and bioactive ingredient.

It is used across pharmaceutical, nutraceutical, and cosmetic supply chains. In pharmaceutical manufacturing, it is formulated into oral joint health supplements and prescription-grade preparations targeting cartilage support.

Consistent molecular weight and sulfation degree are critical to product registration in these sectors. Nutraceutical producers incorporate it into combination joint formulas alongside glucosamine, requiring tight specification control.

This ensures label claim compliance for high-end dietary supplements. In topical cosmetic formulations, it acts as a film-forming humectant that binds moisture to the skin surface, appearing in serums and eye creams.

It is also a key component in anti-aging products. Ophthalmic applications represent a specialized market segment, where high-purity grades are used in eye drops and surgical viscoelastic solutions for medical procedures.

Sodium chondroitin sulfate is supplied as a white to off-white powder. Standard grades include pharmaceutical (USP/BP/Ph. Eur.), food-grade, and cosmetic-grade, with purity typically specified at 90% or higher.

Molecular weight fractions and source declarations are commonly specified by buyers. These details help manufacturers meet regional regulatory and labeling requirements for bovine, porcine, shark, or chicken sources.
