What molecule am I?

伪-罢别谤辫颈苍别辞濒 is a terpene alcohol that is found in natural oils such as pine oil and petitgrain (the oil from the bitter orange tree). It is the most common of four structural isomers; the others are 尾-, 纬-, and 4-terpineol. It should not be confused with terpinol, the hydrate of terpin, a terpene diol.
伪-罢别谤辫颈苍别辞濒 is a racemic mixture of (R)-(+)- and (S)-(鈥�)-enantiomers. Both are found in nature; but the article of commerce, which is usually synthesized from 伪-pinene, is the racemate. In 1903, German chemists H. Waldbaum and O. H眉thig isolated the (+)-stereoisomer from petitgrain. Four years later, J. E. Teeple of New York City separated its enantiomer from聽.
The lilac-like aroma of 伪-terpineol makes it a desirable ingredient for perfumes and cosmetics. This time of year, people burn 伪-terpineol-scented candles for their piney scent. Whatever your favorite aroma during the holidays, enjoy the season!
