Regulatory Record

What each registry publishes about 1-(p-methoxyphenyl)-1-penten-3-one.

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.
