Description

Hyaluronate Octasaccharide CAS NO 57323-43-0 is a precisely defined, low molecular weight oligosaccharide derived from the controlled enzymatic or chemical depolymerization of high molecular weight hyaluronic acid. This specific chain length offers unique biological activity and enhanced bioavailability compared to its larger polymer counterparts, making it a valuable active ingredient and research tool. It is primarily sought after by manufacturers and researchers in the pharmaceutical, advanced cosmeceutical, and nutraceutical industries for its targeted bioactivity.

Application

• Advanced Skincare & Cosmeceuticals: As a key active ingredient in anti-aging serums, moisturizers, and wound-healing formulations due to its superior skin penetration and ability to stimulate collagen production and cellular regeneration.
• Pharmaceutical R&D & Drug Delivery: Utilized in research for osteoarthritis therapeutics, ophthalmic solutions, and as a novel carrier or targeting moiety for drug delivery systems exploiting CD44 receptor interactions.
• Nutraceuticals & Functional Foods: Incorporated into dietary supplements aimed at supporting joint health, skin hydration, and overall connective tissue integrity from within.
• Biomedical Research: Serves as a critical standard and reagent in studies focusing on hyaluronan biology, inflammation, angiogenesis, and cell signaling pathways mediated by low molecular weight hyaluronan fragments.
• Veterinary Medicine: Used in high-performance joint health supplements and therapeutic formulations for companion animals and equine athletes.
