Methyl Anthranilate
Methyl anthranilate is a classic fragrance molecule that combines natural notes with precise laboratory synthesis. It is naturally found in orange blossom, grape, and jasmine, thus possessing a familiar fruity-floral blend. The initial scent evokes the sweet juice of ripe grapes, followed by a light floral note reminiscent of orange blossom and a delicate powdery texture. Often called the “soul of grape fragrances,” it can impart a realistic fruity quality to food and beverages, and create a romantic, soft, and slightly mysterious atmosphere in perfumes.
Type
Fruity
Characterized by grapes, purple grape juice, and grape soda, with hints of orange blossom and jasmine.
Acquisition Methods
Natural extraction or chemical synthesis
It can be extracted from orange blossom oil, grape skins, and jasmine flowers, or it can be prepared by esterification of anthranilic acid with methanol.
