Phenyl-bis-trifluoromethyl-arsin, also known as diphenylarsinic difluoride or (C6H5)2AsF, is an organoarsenic compound characterized by the presence of an arsenic atom bonded to two phenyl groups and two trifluoromethyl groups. This colorless, crystalline solid is a derivative of arsine (AsH3) and exhibits a planar structure due to the sp2 hybridization of the arsenic atom. Phenyl-bis-trifluoromethyl-arsin is primarily used as a precursor in the synthesis of various organoarsenic compounds, which have applications in pharmaceuticals, agrochemicals, and materials science. It is also known for its potential use as a ligand in coordination chemistry. Due to its reactivity and toxicity, handling of Phenyl-bis-trifluormethyl-arsin requires appropriate safety measures and precautions.
The CAS Registry Mumber 655-24-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 5 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 655-24: (5*6)+(4*5)+(3*5)+(2*2)+(1*4)=73 73 % 10 = 3 So 655-24-3 is a valid CAS Registry Number.
