Trans-3′-hydroxy cotinine-d3, also known as 3HC-d3, holds significant importance as a synthetic analog of cotinine, a metabolite derived from nicotine. Cotinine, a prominent component found in tobacco smoke, serves as a biomarker for assessing exposure to tobacco smoke. Operating as an agonist at nicotinic acetylcholine receptors, Trans-3′-Hydroxy Cotinine-d3 exerts its influence in both the central and peripheral nervous systems. By binding to these receptors and activating them, it initiates a cascade of events, leading to the release of neurotransmitters such as dopamine and norepinephrine.
