The Levamisole, with the CAS registry number 14769-73-4, is also known as (S)-2,3,5,6-Tetrahydro-6-phenylimidazo[2,1-b]thiazole. Its EINECS number is 238-836-5. This chemical's molecular formula is C₁₁H₁₂N₂S and molecular weight is 204.29. What's more, its systematic name is (6S)-6-Phenyl-2,3,5,6-tetrahydroimidazo[2,1-b][1,3]thiazole. Its classification codes are: (1)Adjuvants, immunologic; (2)Anthelmintics; (3)Anti-Infective Agents; (4)Antinematodal agents; (5)Antiparasitic Agents; (6)Antirheumatic agents; (7)Drug / Therapeutic Agent; (8)Immunologic Factors; (9)Mutation data. This chemical is used as antihelminthic drug that has been tried experimentally in rheumatic disorders where it apparently restores the immune response by increasing macrophage chemotaxis and T-lymphocyte function. Paradoxically, this immune enhancement appears to be beneficial in rheumatoid arthritis where dermatitis, leukopenia, and thrombocytopenia, and nausea and vomiting have been reported as side effects. It should be sealed and stored at the temperature of 0 - 6 °C.

Physical properties of Levamisole are: (1)ACD/LogP: 1.84; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -0.16; (4)ACD/LogD (pH 7.4): -0.06; (5)ACD/BCF (pH 5.5): 1.00; (6)ACD/BCF (pH 7.4): 1.00; (7)ACD/KOC (pH 5.5): 2.40; (8)ACD/KOC (pH 7.4): 2.99; (9)#H bond acceptors: 2; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 1; (12)Polar Surface Area: 40.9 Å²; (13)Index of Refraction: 1.713; (14)Molar Refractivity: 60.411 cm³; (15)Molar Volume: 154.109 cm³; (16)Polarizability: 23.949×10^-24cm³; (17)Surface Tension: 54.1 dyne/cm; (18)Density: 1.326 g/cm³; (19)Flash Point: 162.076 °C; (20)Enthalpy of Vaporization: 58.834 kJ/mol; (21)Boiling Point: 344.382 °C at 760 mmHg; (22)Vapour Pressure: 0 mmHg at 25°C.
