Diisocyanato-diphenyl-silane, also known as bis(4-isocyanatophenyl)silane, is an organosilicon compound with the chemical formula (C6H5NCO)2SiH2. It is a colorless to pale yellow crystalline solid that is sensitive to moisture and air. diisocyanato-diphenyl-silane is primarily used as a coupling agent in the production of composite materials, particularly in the rubber and plastics industries, to improve adhesion between inorganic fillers and organic polymers. It is also employed as a cross-linking agent in the synthesis of various polymers and as a precursor in the preparation of silane-based materials. Due to its reactivity, diisocyanato-diphenyl-silane is typically handled under an inert atmosphere and stored away from heat and light to maintain its stability.

4756-54-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4756-54-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,5 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4756-54:
(6*4)+(5*7)+(4*5)+(3*6)+(2*5)+(1*4)=111
111 % 10 = 1
So 4756-54-1 is a valid CAS Registry Number.

ULTRAVIOLET SPECTROSCOPIC INVESTIGATION OF ISOCYANATO- AND ISOTHIOCYANATO SILANES CONTAINING PHENYL- AND METHYL GROUPS

Veszpremi, Tamas,Barta, Istvan,Nagy, Jozsef

, p. 243 - 250 (2007/10/02)

The members of the series R(n)Si(NCO)(4-n) and R(n)Si(NCS)(4-n), where R = -CH3 and -C6H5, were prepared, their ultraviolet spectra recorded and the observed bands assigned.The spectra were compared to those of halogeno derivatives.The similarity of halogen- and pseudohalogeno-groups and difference between the effect of methyl- and phenyl-groups were studied.
