Synthesis
It is produced by the diesterification of sebacic acid (decanedioic acid) with 4-hydroxy-TEMPO.[1]
Public health and medical concerns
In 2024, it was detected as an adulterant in illicitly sold fentanyl in the United States.[2][3] It is capable of inhibiting nicotinic acetylcholine receptors.[4][5] Additionally, it is a potent blocker of L-type calcium channels.[6][7] It is also able to induce dose-dependent hemodynamic alterations.[8] Similar to early calcium channel blockers, it can precipitate adrenergic release.[9]
