Description

Lactose Octaacetate is a fully acetylated derivative of lactose, a disaccharide sugar. This chemical modification significantly alters its solubility and reactivity, making it a valuable intermediate and functional material in advanced synthesis. It is primarily sought by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications requiring a protected sugar moiety or a biodegradable polymer precursor.

Application

• Pharmaceutical Intermediate: Serves as a key protected starting material for the synthesis of complex carbohydrates, prodrugs, and novel active pharmaceutical ingredients (APIs).
• Polymer Chemistry: Acts as a monomer or cross-linking agent for producing biodegradable and bio-based polymers with specific degradation profiles.
• Agrochemical Synthesis: Used in the development of advanced, targeted pesticide and herbicide formulations that leverage sugar-based specificity.
• Chiral Building Block: Provides a readily available chiral template for asymmetric synthesis in fine chemical production.
• Food & Flavor Industry: Employed in research and development for creating modified food additives and non-caloric sweetener analogs.
• Cosmetic Ingredient: Functions as a film-forming agent or a mild exfoliant in high-end skincare formulations.
• Laboratory Reagent: Used as a standard or reagent in analytical chemistry and biochemical research.

Quality Control

Our Lactose Octaacetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, detailing key parameters such as assay, optical rotation, and impurity profiles. Our quality commitment supports applications requiring GMP or ISO compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). The product is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent hydrolysis of the acetyl groups.
