"3,9-Bis-(2,4-dichloro-phenoxy)-2,4,8,10-tetraoxa-3,9-diphospha-spiro[5.5]undecane 3,9-disulfide" is a complex organophosphorus compound with the molecular formula C16H12Cl4O4P2S2. It features a spiro[5.5]undecane core, which is a cyclic structure with five carbon atoms in one ring and five in another, connected at a single point. The compound is characterized by the presence of two 2,4-dichloro-phenoxy groups attached to the 3 and 9 positions of the spiro compound, and a disulfide bridge connecting the 3 and 9 positions as well. This structure contributes to its potential applications in areas such as flame retardancy and as a precursor in the synthesis of other organophosphorus compounds. The compound's specific properties and reactivity are influenced by the presence of the dichloro-phenoxy groups and the disulfide bridge, which can engage in various chemical interactions.
The CAS Registry Mumber 5305-88-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 5 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 5305-88: (6*5)+(5*3)+(4*0)+(3*5)+(2*8)+(1*8)=84 84 % 10 = 4 So 5305-88-4 is a valid CAS Registry Number.
