FAQ
Dimethyl carbonate (C3H6O3, CAS 616-38-6) is a clear colourless carbonate ester; UBE produces it via its proprietary nitrite route from carbon monoxide and methanol.
Battery/electronic grade and industrial grade; exact purity, water and colour limits are stated on each lot COA.
Yes, it is a flammable liquid: UN 1161, Class 3, PG II, flash point 17 °C. Shipments follow dangerous-goods handling and earthing rules.
200 kg drums, 1000 L IBC totes, ISO tanks and bulk tanker; small samples in sample cans.
Its polarity and solvency are comparable and it is VOC-exempt in the United States; run a formulation trial before switching.
COA (assay, water, colour), SDS, packing list, and lot number traceable to the UBE production batch.
