DP1(Dipropargyl R-amino indane)

DP1 (Dipropargyl R-amino indane) is a chiral indane derivative featuring a 1-amino group substituted at the R-configuration carbon, with two propargyl moieties attached to the indane core. The molecule exhibits a fused benzene and cyclohexene ring system, with terminal alkynyl groups conferring enhanced lipophilicity. As an API impurity, it arises via nucleophilic substitution pathways during parent drug synthesis, introducing stereochemical and regiochemical complexity. This compound serves as a critical HPLC reference standard for quantifying enantiomeric purity in pharmaceutical processes.
