- Benzoin or 2-Hydroxy-2-phenylacetophenone or 2-Hydroxy-1,2-Diphenylethanone or desyl alcohol or bitter almond oil camphor is an organic compound consisting of an ethylene bridge flanked by phenyl groups and with a hydroxyl and a ketone functional group. It comes as off-white crystals, with a light camphor odor. Benzoin is synthesized from benzaldehyde in the benzoin condensation.
- Benzoin resin or styrax resin is a balsamic resin obtained from the bark of several species of trees in the genus Styrax. It is used in perfumes, some kinds of incense, and medicine. It principally contains benzoic acid. Commonly called "benzoin", it is called "benzoin resin" here to distinguish it from the crystalline compound benzoin. Benzoin resin does not contain this crystalline compound.
- There are two types of benzoin resin used in incense and perfumery, benzoin Siam and benzoin Sumatra. Benzoin Siam is obtained from the Styrax tonkinensis Craib found across Thailand, Laos, Cambodia, and Vietnam. Benzoin Sumatra is obtained from the Styrax benzoin Dryand. grown on the island of Sumatra. Both varieties are pathogenic resins, which are exuded from the tree when it is damaged.
- Benzoin resin is a common ingredient in incense making and perfumery because of its aroma and fixtative properties. Gum benzoin is a major component of the type of church incense used in Russia and some other Orthodox Christian societies. Benzoin resin is also used in blended types of Japanese incense, Indian incense, and Chinese incense. When called sambrani or sambraani, it's a popular Indian incense used to scent and treat hair and prevent infections.
- The benzoin condensation was originally discovered by using cyanide ion as a catalyst. The reaction also can be performed using thiamin. The benzoin condensation is one of the most important reactions of biochemistry, it is the central reaction in sugar biosynthesis and metabolism. It is catalysed by thiamin in living systems, not cyanide.
- Benzoin (I), having both a secondary alcohol and a ketone functional group can be oxidized to a diketone, benzil (II), or reduced to a diol, hydrobenzoin (III). Sodium borohydride, is used for the reduction.
- Benzoin has well-established uses in both allopathic and traditional forms of medicine. Several national pharmacopoeias - including the British, Chinese, French, Italian, Japanese, Swiss, Thai and US - describe specifications and tests for benzoin. Although most imports of benzoin into Malaysia are of block benzoin for direct use as a source of incense, one fragrance compounder purchases benzoin extract for the production of joss stick perfumes. A little benzoin extract goes a long way, however, and in the case of Malaysia, less than 100 kg of extract are purchased per year.
