High purity Hyaluronic Acid (HA) is manufactured by bacterial fermentation. HA has carboxylic acid groups useful for bioconjugation or further derivatization with primary amines. Hyaluronan (Hyaluronate) is an anionic, non-sulfated glycosaminoglycan distributed throughout connective, epithelial, and neural tissues. HA is a most common polysaccharide biopolymer in biomedical research. Applications include drug delivery, hydrogel, tissue engineering, regenerative medicine and soft implant and contact lens. HA has a general CAS# 9004-61-9.


Name and Source: Hyaluronic acid (HA, Hyaluronan, Hyaluronate) is an anionic, non-sulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. CAS# 9004-61-9. Our HA products are produced via microbial fermentation. See Documents section for details.

Appearance: White, lyophilized powder.

Solubility: Soluble in water and the solubility data varies with MW. Higher MW results in lowered solubility. Typically solubility ranges 5-50 mg/mL, that is, 0.5%-5%. Buffered solution at pH >6 enhances solubility due to deprotonation of carboxylic acid groups and formation of carboxylate salts. HA derivatives with hydrophobic groups will lower the solubility in water, and adding alcohol or DMSO to an alcohol-water or DMSO-water mixture can dramatically improve the solubility up to 200 mg/mL (20%).
