Dobutamine Hydrochloride
Dobutamine hydrochloride is a synthetic catecholamine derivative used primarily as a hormone in cardiac stress testing and heart failure treatment. It falls under HTS 2937.90.2000 due to its classification as a structural analogue of catecholamines with inotropic hormonal effects on beta-1 receptors. As a separate chemically defined compound, it aligns with Chapter 29 hormone provisions.
