Reported in EPA TSCA Inventory.
The Quinine, with the CAS registry number 130-95-0 and EINECS registry number 205-003-2, has the systematic name of (8α,9R)-6'-methoxycinchonan-9-ol. And the molecular formula of this chemical is C20H24N2O2. It is a kind of white to light yellow crystal powder. In addition, it is very sensitive to ultraviolet light (UV) and will fluoresce in direct sunlight, due to its highly conjugated resonance structure.
The physical properties of Quinine are as following: (1)ACD/LogP: 3.44; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 0.35; (4)ACD/LogD (pH 7.4): 1.6; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 3.48; (7)ACD/KOC (pH 5.5): 1.45; (8)ACD/KOC (pH 7.4): 25.45; (9)#H bond acceptors: 4; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 5; (12)Polar Surface Area: 34.59 Å2; (13)Index of Refraction: 1.638; (14)Molar Refractivity: 95.78 cm3; (15)Molar Volume: 266.3 cm3; (16)Polarizability: 37.97×10-24cm3; (17)Surface Tension: 56 dyne/cm; (18)Density: 1.21 g/cm3; (19)Flash Point: 253.7 °C; (20)Enthalpy of Vaporization: 80.41 kJ/mol; (21)Boiling Point: 495.9 °C at 760 mmHg; (22)Vapour Pressure: 1.19E-10 mmHg at 25°C.
Preparation and uses of Quinine: The bark of the cinchona tree is the only known natural source of quinine. It is a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels.
You should be cautious while dealing with this chemical. It irritates eyes, respiratory system and skin, and it is also harmful if swallowed. Therefore, you had better take the following instructions: Wear suitable gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice.
