((1S,3R)-3-(Aminomethyl)cyclopentyl)methanol hydrochloride

((1S,3R)-3-(Aminomethyl)cyclopentyl)methanol hydrochloride is a chiral cyclopentane derivative and the hydrochloride salt of an amino alcohol. It is widely used as a pharmaceutical intermediate, particularly in the synthesis of antiviral nucleoside analogs and other biologically active compounds. The defined (1S,3R) stereochemistry is important for obtaining the desired biological activity in target molecules, while the hydrochloride salt form provides improved stability and handling during chemical synthesis. This compound is primarily used in research and pharmaceutical manufacturing rather than as an active drug itself.
