1. Product Introduction & Main Application
Arnico’s Dimethoxymethane (DMM) with a purity of 99.5% is a clear, volatile, and highly flammable liquid used as a polar solvent, methylating agent, and green chemical intermediate in the pharmaceutical and chemical industries, as well as an oxygenated diesel fuel additive. By enabling cleaner combustion and reducing soot, this substance is a modern, environmentally friendly alternative to chlorinated solvents and a cetane improver for diesel.

3. Features & Benefits
-
Polar & Protic Solvent: Provides excellent solubility for resins, adhesives, and polar polymers, acting as a safer replacement for dichloromethane.
-
Anhydrous Formaldehyde Source: An effective methylating and formylating agent in pharmaceutical synthesis, eliminating the need for formaldehyde gas.
-
Diesel Combustion Improver: Adding it to gas oil results in a reduction of Particulate Matter (PM) and soot by up to 40%.
-
Suitable Volatility & Fast Evaporation: Ideal for use in quick-drying coatings and printing inks.
4. Industrial Applications
-
Pharmaceutical Industry: A methylating reagent in the synthesis of APIs (e.g., Metformin).
-
Chemical Industry: A green solvent in the production of fragrances, flavors, and chemical intermediates.
-
Fuel & Energy: An oxygenated additive for diesel fuel and a cetane number improver.
-
Adhesive & Coating Production: A solvent in the formulation of PU-based adhesives and acrylic resins.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This liquid is highly flammable (Flash Point ≈ -18°C) and volatile. Inhalation of its vapors is hazardous. A thorough study of the Arnico MSDS is mandatory.
-
Storage Conditions: Store in completely sealed containers under a nitrogen atmosphere, in a cool environment (below 20°C), away from sparks and strong oxidizing agents. Equipment must be explosion-proof.
-
Personal Protective Equipment (PPE): The use of a respirator with an A-type filter, Viton gloves, and anti-static clothing is mandatory when handling.
6. Quality Assurance & COA
Arnico Dimethoxymethane shipments are accompanied by a Certificate of Analysis (COA) with a precise GC analysis.
