Is dimethyl dicarbonate vegan?

Dimethyl dicarbonate, also known as DMDC or food additive E242, is a synthetic chemical compound used primarily as a beverage preservative and cold sterilizing agent. It is manufactured industrially through chemical synthesis, typically by reacting methyl chloroformate with sodium hydroxide in an aqueous solution. Beverage producers use it to inhibit microorganisms such as yeasts, bacteria, and molds. It most commonly appears on the ingredient labels of wines, ciders, carbonated soft drinks, sports beverages, ready-to-drink teas, and fruit juices.

dimethyl dicarbonate is vegan because it originates completely from synthetic and mineral inputs. No animal tissues, animal byproducts, or animal-derived processing aids are involved in its manufacturing process, and no animal-derived sources of the compound exist. Consequently, it is entirely suitable for a vegan diet.
