Description

L(+)-Ascorbic Acid 2-Sulfate Disodium Salt Dihydrate is a chemically modified, water-soluble derivative of Vitamin C (ascorbic acid) designed for enhanced stability and specific biochemical applications. This compound is valued for its role as a stabilized source of ascorbate in complex formulations where standard ascorbic acid is prone to degradation. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and advanced cosmetic industries for research, diagnostic reagent production, and specialized supplement development.

Application

• Pharmaceutical Research & Intermediate: Used as a key intermediate or reference standard in the synthesis and development of novel therapeutic agents and diagnostic kits.
• Nutraceutical & Dietary Supplement Formulations: Incorporated into specialized supplement products where a more stable or sulfated form of Vitamin C is required for targeted bioavailability.
• Biochemical Research & Cell Culture: Serves as a component in defined media and buffers for studying sulfate transport, enzyme kinetics, and antioxidant mechanisms in vitro.
• Cosmetic Science: Employed in advanced skincare research for developing stabilized antioxidant complexes that protect against environmental oxidative stress.
• Diagnostic Reagent Manufacturing: Acts as a precise reagent in clinical chemistry assays and diagnostic test strips requiring a calibrated ascorbate source.

Quality Control

Our L(+)-Ascorbic Acid 2-Sulfate Disodium Salt Dihydrate is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for research and manufacturing applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to ensure traceability and 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
