Description

Gaultherin CAS NO 490-67-5 is a natural phenolic glycoside compound, also known as methyl salicylate 2-O-β-D-glucoside, primarily extracted from plants of the genus *Gaultheria*. This compound is valued for its role as a precursor to methyl salicylate, a key molecule with recognized anti-inflammatory and analgesic properties. It serves as a critical high-purity reference standard and active ingredient for research and development in the pharmaceutical, nutraceutical, and cosmetic industries, where consistent quality and reliable supply are paramount.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for quality control, method validation, and analytical research in drug development.
• Natural Product Research: A key compound for studying biosynthesis pathways, metabolic processes, and the pharmacological activities of plant-derived salicylates.
• Nutraceutical Formulation: Incorporated into dietary supplements targeting joint health and inflammation management due to its metabolic relationship to salicylates.
• Cosmetic & Topical Applications: Serves as a source ingredient in formulations for creams, gels, and balms designed for soothing muscular discomfort.
• Flavor & Fragrance Intermediate: Used in the synthesis and study of methyl salicylate, which is applied in food flavoring and aromatic products.
• Academic & Institutional Research: Essential for biochemical, pharmacological, and phytochemical studies in university and laboratory settings.
