Triphenyl-trichloracetoxy-silan, also known as trichloro(triphenylsilyl) acetate, is a chemical compound with the molecular formula C20H15Cl3OSi. It is a colorless, crystalline solid that is sensitive to moisture and air. Triphenyl-trichloracetoxy-silan is primarily used as a silylating agent in organic synthesis, particularly in the protection of alcohols and carboxylic acids. Triphenyl-trichloracetoxy-silan is prepared by the reaction of triphenylchlorosilane with trichloroacetic acid. It is an important reagent in the formation of silyl ethers and esters, which are crucial intermediates in various chemical transformations. Due to its reactivity, it is essential to handle Triphenyl-trichloracetoxy-silan with care, typically under an inert atmosphere or in a dry box.
The CAS Registry Mumber 6401-07-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 1 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6401-07: (6*6)+(5*4)+(4*0)+(3*1)+(2*0)+(1*7)=66 66 % 10 = 6 So 6401-07-6 is a valid CAS Registry Number.
