• 使用

  Undecanal is a flavoring agent that is a liquid, colorless or pale yellow, with a sweet odor. it is soluble in most fixed oils, mineral oil, and propylene glycol; insoluble in glycerin. it is obtained by chemical synthesis. it is also termed aldehyde c-11 undecyclic and n-undecyl aldehyde.

• 製造方法

  Usually prepared by oxidation of the corresponding alcohol or reduction of the corresponding acid.

• 定義

  ChEBI: Undecanal is a saturated fatty aldehyde formally arising from reduction of the carboxylic acid group of undecanoic acid. It is a component of essential oils from citrus plants like Citrus reticulata. It has a role as an antimycobacterial drug, a volatile oil component and a plant metabolite. It is a saturated fatty aldehyde, a n-alkanal and a medium-chain fatty aldehyde. It is a tautomer of an undec-1-en-1-ol.

• 一般的な説明

  Undecanal is a volatile flavor compound identified in grapefruit oil and orange essential oil. It is used as a pharmaceutical intermediate.

• 危険性

  Toxic by ingestion and inhalation, irritant to tissue.

• 安全性プロファイル

  Low toxicity by ingestion and skin contact. A skin irritant. Combustible liquid when exposed to heat or flame. To fight fire, use CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
