Summary
First definitively identified in Austria in January 2022 and sold online as racemic trans-diastereomer (approximately 90% assay purity). No peer-reviewed pharmacodynamic studies yet exist; structure-activity relationships and subjective reports suggest potency slightly lower than 4-methylaminorex but still active at sub-25 mg doses. User reports from Bluelight and research forums indicate threshold effects at 2-4 mg insufflated and functional amphetamine-like stimulation around 15-25 mg with 12-18 hour wakefulness but modest euphoria. Analytical characterization confirms bromine isotopic LC-HRMS signature (m/z 255.0133 [M+H]+) and chiral separation reveals racemic trans-diastereomer form. Purity differences between batches (85-98%) warn of potential inactive filler or active by-products.
