Identification of a Unique Glucosylsulfate Conjugate Metabolite of Profenofos in Cotton

The major metabolic pathway for profenofos in cotton involves cleavage of the phosphorothioate ester to yield 4-bromo-2-chlorophenol followed by conjugation with sugars. This investigation found a unique sugar conjugate in cotton stalks and seed. The unique metabolite is identified as a glucosylsulf...

Zusammenfassung:	The major metabolic pathway for profenofos in cotton involves cleavage of the phosphorothioate ester to yield 4-bromo-2-chlorophenol followed by conjugation with sugars. This investigation found a unique sugar conjugate in cotton stalks and seed. The unique metabolite is identified as a glucosylsulfate conjugate of 4-bromo-2-chlorophenol, and its isolation and structure elucidation are reported. Keywords: Organophosphate metabolism; cotton plants; conjugation reactions; O-glucosylsulfate formation
