Can 2-Acetylpyridine be labeled natural?

The process decides for 2-Acetylpyridine. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic 2-Acetylpyridine is artificial. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic 2-Acetylpyridine identical-to-natural.
