Description

Dimethyl Dicarbonate CAS NO 4525-33-1 is a highly reactive chemical ester primarily used as a potent antimicrobial agent and sterilant. Its core value lies in its ability to effectively inactivate a broad spectrum of microorganisms, including yeast, bacteria, and molds, without leaving significant residues. This makes it an essential processing aid for manufacturers requiring microbial stability and extended shelf-life. Key industries that rely on this compound include beverage production, food processing, and pharmaceutical manufacturing where aseptic conditions are critical.

Application

• Beverage Cold Sterilization: Primary use as a microbial control agent in wines, ready-to-drink teas, isotonic drinks, and fruit juices to prevent spoilage.
• Food Preservation: Application in liquid food products, sauces, and fillings to inhibit yeast and bacterial growth without thermal processing.
• Pharmaceutical Processing: Used as a sterilizing agent for non-heat-stable solutions and equipment in aseptic manufacturing environments.
• Cosmetic & Personal Care: Preservation of water-based formulations to ensure product safety and longevity.
• Industrial Biocide: Control of microbial contamination in process water, cooling systems, and other industrial aqueous systems.
• Laboratory Research: Employed as a biochemical tool for enzyme inhibition studies and metabolic pathway analysis.

Quality Control

Our Dimethyl Dicarbonate is manufactured and tested under strict quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay purity, identity confirmation, and impurity profiles. The product is suitable for applications requiring compliance with food safety regulations (e.g., FCC, FDA 21 CFR) and relevant pharmacopeial guidelines where applicable. For specific grade requirements or regulatory support documentation, please contact our technical team.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 2°C and 8°C (refrigerated). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain stability and prevent decomposition. Keep away from heat, sparks, and open flames. Isolate from incompatible materials such as strong bases, amines, and reducing agents.
