Dicyclohexyldifluorosilane, also known as bis(1,4,7,10-tetraazacyclododecane)difluorosilane, is an organosilicon compound with the chemical formula (C6H11)2SiF2. It is a colorless liquid that is soluble in organic solvents and has a molecular weight of 266.37 g/mol. dicyclohexyldifluorosilane is primarily used as a coupling agent in the production of silicone rubber, where it helps to improve the adhesion between the rubber and various substrates, such as metals, glass, and plastics. It is also employed as a cross-linking agent in the synthesis of certain polymers and as a reagent in organic synthesis. Due to its reactivity with water, dicyclohexyldifluorosilane must be handled with care and stored under anhydrous conditions to prevent hydrolysis.
The CAS Registry Mumber 339-28-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 9 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 339-28: (5*3)+(4*3)+(3*9)+(2*2)+(1*8)=66 66 % 10 = 6 So 339-28-6 is a valid CAS Registry Number.
