Specification
The Xylazine is an organic compound with the formula C12H16N2S. The IUPAC name of this chemical is N-(2,6-dimethylphenyl)-5,6-dihydro-4H-1,3-thiazin-2-amine. With the CAS registry number 7361-61-7, it is also named as 4H-1,3-thiazin-2-amine, N-(2,6-dimethylphenyl)-5,6-dihydro-. The product's classification codes are Adrenergic Agents; Adrenergic Agonists; Adrenergic alpha-agonists; Drug / Therapeutic Agent; Human Data; Neurotransmitter Agents.
In veterinary anesthesia, Xylazine is often used in combination with ketamine. It is a drug that is used for anesthesia, sedation, muscle relaxation, and analgesia in animals such as horses, cattle and other non-human mammals. As with other α2 agonists, adverse effects include bradycardia, conduction disturbances and myocardial depression. As an emetic, it is desirable to remove a substance from a cat's stomach.
Physical properties about Xylazine are: (1)ACD/LogP: 2.37; (2)ACD/LogD (pH 5.5): 0.59; (3)ACD/LogD (pH 7.4): 1.92; (4)ACD/BCF (pH 5.5): 1; (5)ACD/BCF (pH 7.4): 13.3; (6)ACD/KOC (pH 5.5): 7.74; (7)ACD/KOC (pH 7.4): 165.43; (8)#H bond acceptors: 2; (9)#H bond donors: 1; (10)#Freely Rotating Bonds: 1; (11)Polar Surface Area: 40.9 Å2; (12)Index of Refraction: 1.611; (13)Molar Refractivity: 66.29 cm3; (14)Molar Volume: 190.9 cm3; (15)Polarizability: 26.28×10-24cm3; (16)Surface Tension: 40.6 dyne/cm; (17)Density: 1.15 g/cm3; (18)Flash Point: 155.9 °C; (19)Enthalpy of Vaporization: 57.72 kJ/mol; (20)Boiling Point: 334.2 °C at 760 mmHg; (21)Vapour Pressure: 0.00013 mmHg at 25°C.
