Also known as 2,5-DIMETHOXY-N,N-DIMETHYL-4-IODOAMPHETAMINE
IDNNA was developed as a potential brain-imaging agent and proved pharmacologically inert, showing none of the psychedelic effects of its close relative DOI even at comparable doses in a quiet human test. It behaved well as a brain-uptake tracer, going in fast and staying put, without measurable mental activity.
