用途スイートピー様香料として重要であり、特にセッケン香料として用いる。
天然物の起源Occasionally Benzalacetone is used in perfumery for Sweet Pea (used to be a “must” in this type of fragrance), in Appleblossom, etc., often in combination with Neroli and Hyacinth bases. Also used in flavors, particularly in Chocolate, Cocoa, Cherry, Fruit, Nut, Vanilla, etc. - but usually at very low concentration. Concentration in finished product will rarely exceed 0.2 to 0.5 ppm.
使用brightener in acid zinc electroplating,also used as an organic synthesis intermediate in flavor and fragrance, pharmaceutical industries
一般的な説明trans- 4-Phenyl-3-buten-2-one is substrate for glutathione transferase. It reacts with methyl- and benzylguanidine to yield aromatic N2-substituted 2-pyrimidinamines.

化学的特性Yellow Solid
製造方法By condensing benzaldehyde and acetone in the presence of an alkaline condensing agent.
純化方法Crystallise it from pet ether (b 40-60o), or distil it (b 137-142o /16mm). [Beilstein 7 IV 1003.]
定義ChEBI: Trans-benzylideneacetone is the trans-isomer of benzylideneacetone. It acts as an inhibitor of the enzyme phospholipase A2 (EC 3.1.1.4) of insects like diamond back moth. It has a role as a flavouring agent, a fragrance, a bacterial metabolite and an EC 3.1.1.4 (phospholipase A2) inhibitor.
