Description

Cellobionolactone is a specialized carbohydrate derivative and lactone of cellobionic acid. This compound serves as a valuable chiral building block and intermediate in advanced organic synthesis and biochemical research. It is particularly relevant for industries focused on fine chemicals, pharmaceutical development, and carbohydrate chemistry, where high-purity intermediates are critical for process success.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug candidates, particularly those targeting carbohydrate-based biological pathways.
• Biochemical Research: Acts as a substrate or inhibitor in enzymatic studies involving glycosidases or carbohydrate-processing enzymes.
• Fine Chemical Synthesis: Serves as a chiral precursor for the production of complex organic molecules, surfactants, and specialty polymers.
• Cosmetic Ingredient: Potential use in high-end skincare formulations for its mild exfoliating and moisturizing properties derived from its sugar acid structure.
• Food Science Research: Investigated for its role as a potential prebiotic or functional food additive due to its lactone form of a cellobiose derivative.
• Material Science: Explored as a monomer for biodegradable polymers or as a component in advanced hydrogel matrices.

Quality Control

Our Cellobionolactone is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. We adhere to cGMP principles where applicable, and specifications can be aligned with customer-specific requirements for research or commercial use.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can lead to hydrolysis of the lactone ring.
