Dimethyl Dicarbonate
Dimethyl Dicarbonate (DMDC), with the molecular formula C4H6O5 and molecular weight of 118.10 g/mol, is a food-grade antimicrobial agent used primarily in beverage preservation. It is supplied as a clear, colorless liquid with a slight ester odor and is stable under controlled storage conditions. The product is handled as a reactive ester and requires dry, cool environments to prevent hydrolysis.
DMDC decomposes into methanol and carbon dioxide after application, leaving no residual taste or odor in finished products. This makes it suitable for use in wine, fruit juices, and non-alcoholic beverages where sensory integrity is critical. In industry practice, typical usage levels range from 100 to 250 mg/L, depending on microbial load and pH. It is not used in products with high water activity above 0.95 without careful formulation control.
Buyers in the beverage manufacturing sector, particularly in Europe and North America, source DMDC for shelf-life extension without altering flavor profiles. It is typically packed in 200 kg HDPE drums or 1000 kg IBC totes. Trade terms commonly offered are FOB Shanghai or CIF destination port. Buyers should confirm the batch-specific Certificate of Analysis for residual methanol and purity levels prior to use.

Sourcing Dimethyl Dicarbonate from Lianyungang Huaihua International Trade Co., Ltd. - China Import Guide
Before placing an order, confirm the batch-specific Certificate of Analysis for purity, residual methanol, and water content. Request a copy of the supplier's internal quality control protocol and verify that testing is performed by an accredited third-party lab. Do not rely on generic compliance claims without supporting data. Ensure the product matches the CAS number 553-71-9 and molecular weight of 118.10 g/mol.
Confirm the Incoterms, shipping method, and lead time directly with the supplier. Common terms include FOB Shanghai or CIF destination port. Lead times typically range from 15 to 25 days after payment confirmation. Payment is often via T/T in advance or LC at sight. Always require a bill of lading and export declaration that matches the product description and quantity.
Perform incoming inspection by testing a sample for active content and methanol levels using GC. Verify packaging integrity, labeling accuracy, and seal condition upon arrival. Retain a sample for 12 months for potential quality disputes. Request a copy of the SDS in English and ensure it aligns with GHS standards. Document all inspection results and retain them for regulatory audits.
