Description

Hyaluronic Acid Tetrasaccharide Ammonium Salt is a precisely defined, low-molecular-weight oligosaccharide derivative of hyaluronic acid. This compound is valued for its enhanced bioavailability and targeted biological activity compared to high-molecular-weight polymers. It serves as a critical raw material and research standard for advanced applications in the cosmetic, pharmaceutical, and nutraceutical industries, where precise molecular structure and purity are paramount for efficacy and safety.

Application

• Cosmetic Actives: Key ingredient in anti-aging serums, moisturizers, and dermal fillers for deep skin hydration and stimulation of collagen synthesis.
• Pharmaceutical Research: Used as a standard or intermediate in the development of novel drug delivery systems and therapies targeting inflammation, wound healing, and osteoarthritis.
• Biomedical Studies: Essential tool in cell culture and molecular biology research to study hyaluronan-receptor interactions (e.g., CD44, RHAMM) and signaling pathways.
• Nutraceutical Formulations: Incorporated into dietary supplements aimed at supporting joint health, skin vitality, and overall connective tissue function.
• Advanced Material Science: Building block for creating functionalized hydrogels, biocompatible coatings, and smart biomaterials with specific degradation profiles.
