Antimony, difluorotris(4-methylphenyl)-, also known as antimony(III) tri-p-tolyl, is a chemical compound with the formula (C7H7)3SbF2. It is a derivative of antimony, a metalloid element, and features three 4-methylphenyl (p-tolyl) groups and two fluorine atoms bonded to the central antimony atom. This organoantimony compound is characterized by its stability and unique electronic properties, which make it a subject of interest in various chemical research areas, including organometallic chemistry and materials science. The compound is typically synthesized through the reaction of antimony trichloride with lithium and p-tolyllithium, and it is used in the preparation of other organoantimony compounds and as a precursor in the synthesis of certain organic compounds.

373-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 373-85-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 373-85:
(5*3)+(4*7)+(3*3)+(2*8)+(1*5)=73
73 % 10 = 3
So 373-85-3 is a valid CAS Registry Number.

Triarylantimony difluorides were synthesized in moderate to excellent yields by oxidative fluorination of triarylstibanes with nitrosyl tetrafluoroborate (NOBF4) under aerobic conditions. This reaction is the first example of fluorination of trivalent organoantimony compounds using NOBF4 as a fluorinating agent. The triarylantimony difluorides exhibited good anti-proliferation activity against tumor cell lines. In particular, the IC50 of p-Tol3SbF2 (2c) was the lowest in each cell lines.
