描述
Phenylephrine HCl (CAS: 61-76-7) is a white crystalline powder with the molecular formula C₉H₁₄ClNO₂ (molecular weight: 203.67). As a selective α₁-adrenergic agonist, it is widely used as a vasoconstrictor in pharmaceuticals, primarily for treating nasal congestion (decongestant) and hypotension. Its mechanism involves binding to α₁-receptors, inducing vasoconstriction. The compound is water-soluble (≥10 g/100 mL at 21°C) and stable under dry conditions. Pharmaceutical-grade phenylephrine HCl typically exhibits ≥98% purity, with applications extending to ophthalmic solutions (pupil dilation) and injectable formulations. Also known as L-Phenylephrine hydrochloride, it is recognized as an R-(-)-enantiomer (optical rotation: [α]²⁴ᴅ = -45.5°). Storage recommendations include desiccated environments at room temperature or 2–8°C。
