Description

D-Galactose is a naturally occurring monosaccharide sugar, a critical building block in glycobiology and a key component of many biological molecules. Its high purity and consistent quality make it an essential raw material for research and industrial processes requiring precise biochemical interactions. This product is vital for manufacturers and researchers in the pharmaceutical, nutraceutical, and food science industries, where it serves as a precursor for synthesis, a culture medium component, and a nutritional supplement.

Application

• Pharmaceutical Synthesis: As a chiral starting material or intermediate in the production of active pharmaceutical ingredients (APIs), diagnostic agents, and complex carbohydrates.
• Cell Culture & Microbiology: Used as a carbon source in specialized culture media for the growth of microorganisms and mammalian cells in bioprocessing and research.
• Nutraceutical & Dietary Supplements: Incorporated into infant formula and specialized nutritional products to replicate the oligosaccharide profile of human milk.
• Biochemical Research: Essential for studying carbohydrate metabolism, enzymatic activity (e.g., galactosidases), and glycoprotein structure-function relationships.
• Food Science: Employed as a mild sweetener and a texturizing agent, and in the study of Maillard reaction products for flavor development.
• Cosmetic Formulations: Used in skincare products for its potential moisturizing and skin-conditioning properties.

Quality Control

Our D-Galactose is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. It can be manufactured to meet various grade specifications, including high-purity standards suitable for pharmaceutical applications. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
