Abstract
HPLC-HRMS method for detection of Furanoylfentanyl and its metabolites in the urine is developed. For this it is proposed the implementation of an approach using targeted searches for finding the most probable metabolites, basing on their calculated exact mass and fragmentation regularities. HRMS spectrum of Furanoylfentanyl and its metabolites are obtained.
