Specification
Xanthine, with the CAS Number 69-89-6, is a yellowish-white, crystalline purine base. Xanthine is a purine base found in most human body tissues and fluids and in other organisms. Xanthine is a product on the pathway of purine degradation. It is created from guanine by guanine deaminase; from hypoxanthine by xanthine oxidoreductase or from xanthosine by purine nucleoside phosphorylase(PNP).
Physical properties about Xanthine are: (1)ACD/LogP: -0.13; (2)ACD/LogD (pH 5.5): -3.63; (3)ACD/LogD (pH 7.4): -3.63; (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: 6; (9)#H bond donors: 3; (10)Index of Refraction: 1.903; (11)Molar Refractivity: 36.566 cm3; (12)Molar Volume: 78.403 cm3; (13)Polarizability: 14.496 10-24cm3; (14)Surface Tension: 170.186996459961 dyne/cm; (15)Density: 1.94 g/cm3; (16)Flash Point: 458.72 °C; (17)Enthalpy of Vaporization: 125.498 kJ/mol; (18)Boiling Point: 834.882 °C at 760 mmHg
