USE: Piperonal is used as a flavoring and as a scent in perfumes, candles, air fresheners, laundry products, and deodorant. It has also been used in some sunscreens, mosquito repellents, lice treatments and repellants, and to make other chemicals. EXPOSURE: Workers who use piperonal may breathe in mists or have direct skin contact When Darzens condensation was applied to 4-bromocrotontane (138) and piperonal (139), it resulted in vinylogous condensation product (140) (Scheme 1.32).The condensation is proposed to take place via intermediate (141).Alkenyl epoxide-dihydrofuran rearrangement followed by a Lewis acid-mediated reaction with dimethyl acetal of piperonal furnished (+/−) epiasarinin (142). 4

Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds. Notice: Concentration information is not available for this spectrum and, therefore, molar absorptivity values cannot be derived. Additional Dat Preparation. Due to its poor solubility in water, piperine is typically extracted from black pepper by using organic solvents like dichloromethane. However, aqueous extraction can be performed with high yields and selectivity with the use of hydrotrope solutions. The amount of piperine varies from 1-2% in long pepper, to 5-10% in commercial white and black peppers Description Piperonal is found in oils of Spirea ulmaria L., Doriphora sassafras Endl., and other oils. It is prepared by oxidation of isosafrole. It is a white crystalline substance with a sweet floral odour resembling heliotrope and free from safrole by-odour
