PDP-EA is primarily used as a research chemical in forensic and analytical laboratories for the identification and detection of synthetic cannabinoid metabolites. It serves as a reference standard in mass spectrometry and chromatography to help develop methods for screening biological samples such as urine or blood. Its high purity and structural specificity make it valuable for studying metabolic pathways of synthetic cannabinoids and supporting toxicology investigations. Due to its role in detecting designer drugs, PDP-EA aids in public health monitoring and substance abuse research. It is not intended for human consumption or therapeutic use.
