Tris(4-bromophenyl) phosphite is an organophosphorus compound with the chemical formula C18H12Br3O3P. It is a colorless crystalline solid that is soluble in organic solvents. tris(4-bromophenyl) phosphite is characterized by three 4-bromophenyl groups attached to a central phosphorus atom, which is also bonded to an oxygen atom. Tris(4-bromophenyl) phosphite is used as a flame retardant, particularly in the production of polyurethane foams, and as a stabilizer for halogenated polymers. It is also employed as a ligand in organometallic chemistry and as an intermediate in the synthesis of other phosphorus-containing compounds. Due to its bromine content, it can effectively interrupt combustion processes, making it a valuable component in fire safety applications.

Check Digit Verification of cas no

The CAS Registry Mumber 37844-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,8,4 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37844-58:
(7*3)+(6*7)+(5*8)+(4*4)+(3*4)+(2*5)+(1*8)=149
149 % 10 = 9
So 37844-58-9 is a valid CAS Registry Number.

Synthesis of fluorescent (benzyloxycarbonylamino)(aryl)methylphosphonates

Vel Gorniak, Michal Gorny,Czernicka, Anna,Mlynarz, Piotr,Balcerzak, Waldemar,Kafarski, Pawel

, p. 741 - 745 (2014)

The synthesis of a library of structurally variable aromatic esters of (benzyloxycarbonylamino)(aryl)methylphosphonic acids is described by means of the Oleksyszyn reaction. The library was enlarged by the application of a Suzuki-Miayra approach and by preparation of mixed esters.
