Sodium hyaluronate is a high-molecular-weight polysaccharide derived from hyaluronic acid, widely utilized as a viscosupplement and excipient. Synthesized via bacterial fermentation or animal tissue extraction, its chemical structure consists of repeating disaccharide units of D-glucuronic acid and N-acetyl-D-glucosamine. The standard molecular formula is (C14H20NNaO11)n with CAS No. 9004-61-9.
Clinical use requires strict aseptic techniques to prevent infection; contraindicated in patients with severe hypersensitivity to avian proteins. Storage must occur below 25°C in dry conditions to maintain viscosity stability and prevent microbial degradation.
