1-(4-fluoro-phenyl)-4-methylsulfanyl-2-phenyl-5,6,7,8-tetrahydro-quinazolinium; iodide is a complex organic compound with the molecular formula C21H20FN2S+I-. It consists of a quinazolinium ring system, which is a fused ring structure containing a benzene ring, a quinazoline ring, and a tetrahydro ring. The compound features a 4-fluoro-phenyl group attached to the quinazolinium ring, a methylsulfanyl group, and a phenyl group. The iodide counterion is present to balance the positive charge on the quinazolinium cation. This chemical is known for its potential applications in medicinal chemistry, particularly as a precursor or intermediate in the synthesis of various pharmaceuticals and agrochemicals. Its specific properties and reactivity are influenced by the presence of the fluorine atom, which can impart unique electronic and steric effects on the molecule.
The CAS Registry Mumber 5185-20-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,8 and 5 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5185-20: (6*5)+(5*1)+(4*8)+(3*5)+(2*2)+(1*0)=86 86 % 10 = 6 So 5185-20-6 is a valid CAS Registry Number.
