Formula: C17H18Cl2N2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-(Bis(4-chlorophenyl)methyl)piperazine, is researched, Molecular C17H18Cl2N2, CAS is 27469-61-0, about Synthesis and antiallergic activities of diphenylmethylpiperazine derivatives.

The diphenylmethylpiperazine derivatives were designed and synthesized to find high anti-allergic compounds Twenty-one compounds of 1-R3-4-[(4-R1-phenyl)(4-R2-phenyl)methyl]piperazine (R1 = H, Cl, F, methoxy, tert-Bu, or nitro; R2 = H, F, Cl, or tert-butyl; and R3 = Et, benzyl, Bu, octyl, cetyl, or dodecyl), among which 17 compounds were new ones, were designed and synthesized from benzophenone derivatives by reduction with Zn/NaOH, substitution reaction with piperazine, and substitution reaction with R3Br. Their structures were identified by IR, 1H-NMR spectral, and elemental anal. Some compounds were evaluated from two pharmacol. models of the delayed-type hypersensitivity response to 2,4-dinitrochlorobenzene (DNCB) in mice and vascular permeability reduced by histamine in mice. Two compounds (R1 = R2 = H and R3 = Bu or dodecyl) had high antiallergic effects on the delayed-type hypersensitivity, and 5 compounds (R1 = R2 = H, R3 = octyl, cetyl, or dodecyl; R1 = nitro or F, R2 = H or F, R3 = dodecyl) had high antihistamine activity. Antiallergic activity was stronger with longer carbon chains.
