Specification

Scopine, with the CAS NO.498-45-3, is a tropane alkaloid found in a variety of plants including Mandragora root, Senecio mikanoides (Delairea odorata), Scopolia carniolica, and Scopolia lurida. It is also called 1α,2β,4β,5α)-9-Methyl-3-oxa-9-azatricyclo[3.3.1.02,4]nonan-7β-ol;(1β,2α,4α,5β,7α)-9-Methyl-3-oxa-9-azatricyclo[3.3.1.02,4]nonan-7-ol. Scopine can be prepared by the hydrolysis of scopolamine.

Physical properties about Scopine are: (1)ACD/LogP: -0.295; (2)ACD/LogD (pH 5.5): -3.23; (3)ACD/LogD (pH 7.4): -1.82; (4)ACD/BCF (pH 5.5): 1.00; (5)ACD/BCF (pH 7.4): 1.00; (6)ACD/KOC (pH 5.5): 1.00; (7)ACD/KOC (pH 7.4): 1.00; (8)#H bond acceptors: 3; (9)#H bond donors: 1; (10)#Freely Rotating Bonds: 1; (11)Molar Refractivity: 39.857 cm³; (12)Molar Volume: 120.794 cm³; (13)Polarizability: 15.801 10-24cm³; (14)Surface Tension: 46.4469985961914 dyne/cm; (15)Density: 1.285 g/cm³; (16)Flash Point: 123.928 °C; (17)Enthalpy of Vaporization: 60.366 kJ/mol; (18)Boiling Point: 281.303 °C at 760 mmHg
