Applications
Dobutamine hydrochloride is a catecholamine that acts as a β-adrenergic receptor agonist. It has its strongest effects on β1 receptors, with lesser but significant β2 receptor activation and only weak α1 receptor actions. As a result, it strongly increases cardiac contractility with modest chronotropic, arrhythmogenic, and vascular side effects. It is also a polyphenolic antioxidant and can inhibit all human carbonic anhydrase isoforms with Ki values near 1 μM.

Solubility
Soluble in water or ethanol with warming. Also soluble in methanol

Notes
Solutions oxidize readily at pH greater than 11. Protect solutions from light
