This compound combines a sulfur-containing ring (a dithiane) with an aldehyde group, a structure occasionally found among savory, roasted-flavor chemicals. It's used in food as a flavor enhancer and flavoring agent, and the FDA lists it as approved for both.
What each registry publishes about 2,8-dithianon-4-en-4-carboxaldehyde.
Every row comes from a published regulator source, linked so you can read it yourself. "Prohibited" means a regulator has affirmatively banned it; "not authorized" means it has never been cleared for that use there. The two are not the same thing, so we never collapse them.
