General description

Folpet is a contact fungicide used for the control of foliar and seed-borne diseases. Folpet is known to inhibit various oxidative enzymes, carboxylases and also enzymes required for phosphate metabolism and citrate synthesis.

Application

Folpet may be used as a reference standard for the determination of the analyte in food matrices based on QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method for extraction followed by gas chromatography coupled with electron ionization and triple quadrupole mass spectrometry (GC-EI-MS/MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

A novel method was developed for the determination of captan, folpet, and captafol in apples by dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-electron capture detection (GC-ECD). Some experimental parameters that influence the extraction efficiency, such as the type and

Solid-phase extractions followed by HPLC-UV/DAD methods were developed for occupational biological monitoring or forensic investigations of the fungicide folpet using its degradation products, phthalimide and phthalamic acid as plasma biomarkers. These methods show good linearity (r>0.9955), precision (CV<15%) and accuracy
