Description

Alpha,β-Trehalose CAS NO 585-91-1 is a non-reducing disaccharide sugar composed of two glucose molecules, renowned for its exceptional stability and protective properties. This compound matters for its unique ability to stabilize proteins, cells, and other biological structures against damage from dehydration, heat, and freezing. It is a critical ingredient for industries requiring advanced stabilization solutions, including pharmaceuticals, cosmetics, and food technology.

Application

• Pharmaceutical Excipient & Stabilizer: Used as a lyoprotectant in the freeze-drying (lyophilization) of vaccines, antibodies, enzymes, and other sensitive biologics to maintain efficacy and shelf-life.
• Cosmetic & Personal Care: Functions as a highly effective humectant and moisturizer in skincare formulations, helping to protect skin cells from dehydration and environmental stress.
• Food & Beverage Ingredient: Employed as a natural sweetener, texturizer, and shelf-life extender in processed foods, confectionery, and health supplements due to its mild sweetness and low hygroscopicity.
• Diagnostic Reagents & Biotechnology: Serves as a stabilizing agent in diagnostic kits, PCR master mixes, and enzyme preparations to ensure long-term activity and reliability.
• Cell Culture & Cryopreservation: Acts as a cryoprotectant for the freezing and long-term storage of mammalian cells, bacteria, and other sensitive biological samples.
• Agriculture & Seed Coating: Applied in seed treatments and agricultural formulations to enhance seed viability and protect beneficial microorganisms from desiccation.

Quality Control

Our Alpha,β-Trehalose is manufactured under strict quality management systems. It can be supplied to meet various standards including Food Chemical Codex (FCC) and Pharmaceutical (USP/EP) grades, ensuring suitability for high-purity applications. All batches undergo rigorous analytical testing, including HPLC for assay and purity, residual solvent analysis, and microbiological examination. Certificates of Analysis (COA) are provided with each shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
