4-fluoro-trityl, also known as 4-fluorophenyltrityl or 4-fluoro-(triphenylmethyl)benzene, is an organic compound with the chemical formula C19H15F. It is a derivative of trityl, a triphenylmethyl group, with a fluorine atom attached to the para position of the benzene ring. This modification introduces unique electronic and steric properties to the molecule, which can be exploited in various chemical reactions and applications. 4-fluoro-trityl is often used as a protecting group in organic synthesis, particularly in the protection of alcohols and amines, due to its stability and ease of removal under mild acidic conditions. Its fluorine atom can also participate in reactions, such as metal-catalyzed cross-couplings, making it a valuable building block in the synthesis of complex organic molecules.
The CAS Registry Mumber 6060-70-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,6 and 0 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 6060-70: (6*6)+(5*0)+(4*6)+(3*0)+(2*7)+(1*0)=74 74 % 10 = 4 So 6060-70-4 is a valid CAS Registry Number.
