Oxybutynin-d₅ hydrochloride 

Oxybutynin-d₅ hydrochloride is deuterated labeled (R)-Oxybutynin hydrochloride (HY-B0267B). (R)-Oxybutynin hydrochloride, a (R)-isomer of Oxybutynin hydrochloride, is an orally active muscarinic receptor antagonist. (R)-Oxybutynin hydrochloride has antimuscarinic, antispasmodic and anticholinergic activity, competitively antagonizes Carbachol-induced contractions. (R)-Oxybutynin hydrochloride can be used for researching incontinence due to neurogenic bladder dysfunction^[1][2][3]. (R)-Oxybutynin hydrochloride is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

氢、碳和其他元素的稳定重同位素已被纳入药物分子中，主要作为药物开发过程中定量的示踪剂。氘化引起了人们的关注，因为它可能影响药物的药代动力学和代谢谱^[1]。
