Description

Undecyl Maltoside (High Alpha) CAS NO 168037-13-6 is a high-purity, non-ionic surfactant belonging to the alkyl glycoside family, specifically an undecyl maltoside with a high α-anomer content. This compound is valued for its exceptional mildness, biodegradability, and ability to effectively solubilize membrane proteins without denaturing them. It is an essential reagent for research and industrial applications in biochemistry, pharmaceuticals, and advanced material science, where gentle yet powerful detergent properties are required.

Application

• Membrane Protein Solubilization & Crystallization: A critical detergent for extracting and stabilizing integral membrane proteins for structural biology studies, including X-ray crystallography and cryo-electron microscopy.
• Biochemical Research & Assay Development: Used in buffer formulations for enzyme studies, receptor-ligand binding assays, and the purification of sensitive biomolecules due to its low critical micelle concentration (CMC) and high purity.
• Pharmaceutical Formulations: Serves as a mild solubilizing and stabilizing agent in topical, ophthalmic, and injectable drug delivery systems.
• Cosmetic & Personal Care: Employed as a high-performance, skin-friendly surfactant in premium cleansing products, shampoos, and lotions.
• Industrial & Household Cleaners: Acts as a key ingredient in eco-friendly and high-foaming detergent formulations, valued for its excellent wetting and emulsifying properties.
• Agricultural Adjuvants: Used to enhance the efficacy and penetration of pesticides and herbicides in crop protection products.

Quality Control

Our Undecyl Maltoside (High Alpha) is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and alpha/beta anomer ratio, NMR for structural confirmation, and tests for residual solvents and moisture. Certificates of Analysis (COA) detailing all specifications are provided to ensure compliance with research and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture.
