 (və-nĭl′ĭn, văn′ə-lĭn)
n.
A white or yellowish crystalline compound, C8H8O3, found in vanilla beans and certain balsams and resins or produced synthetically and used in perfumes, flavorings, and pharmaceuticals.

vanillin

(ˈvænɪlɪn; vəˈnɪlɪn)
n
(Elements & Compounds) a white crystalline aldehyde found in vanilla and many natural balsams and resins; 3-methoxy-4-hydroxybenzaldehyde. It is a by-product of paper manufacture and is used as a flavouring and in perfumes and pharmaceuticals. Formula: (CH3O)(OH)C6H3CHO
