Identification of 4-bromo-2-chlorophenol as a contaminant responsible for organoleptic taint in melons

Identification of 4-bromo-2-chlorophenol as a contaminant responsible for organoleptic taint in melons. Sanchez Saez, J. J.In this study，3964-56-5 is also used.; Herce Garraleta, M. D.; Calvo Anton, P.; Folgueiras Alonso, M. L. (Natl. Cent. Food Nutr., Natl. Inst. Health 'Carlos III', Majadahonda 28220, Spain). Food Addit. Contam., 8(5), 627-31 (English) 1991. CODEN: FACOEB.

DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 5 An off-odor, described by the growers as similar to profenofos, occurred in melons in which this pesticide had been used in crop treatment. However, profenofos, O-(4-bromo-2-chlorophenyl) O-Et S-prppyl phosphorothioate, could not be detected in the melons using GC/MS, although a component with a shorter retention time was found. Concn. of melon volatiles by steam distn. yielded a product identical to that obtained by hydrolysis of profenofos, identified as 4-bromo-2-chlorophenol. A soln. of this compd. in water had similar organoleptic properties to that of the contaminated fruit. It was concluded that 4-bromo-2-chlorophenol was responsible for the taint detected in melons. .
