2-(N,O-bis-benzyloxycarbonyl-tyrosyl)-1,1-dioxo-1,2-dihydro-1λ6-benzo[d]isothiazol-3-one is a complex organic compound with a molecular formula of C31H25N3O7S. It is a derivative of benzo[d]isothiazol-3-one, featuring a benzene ring fused to an isothiazolone ring. The compound is characterized by the presence of a tyrosyl group, which is protected by two benzyloxycarbonyl groups (N,O-bis-benzyloxycarbonyl). This protection is commonly used in peptide synthesis to prevent unwanted side reactions. The compound has a 1,2-dihydro structure, indicating the presence of a double bond between the two carbon atoms, and a 1,1-dioxo group, which refers to the two oxygen atoms bonded to the same carbon atom. 2-(N,O-bis-benzyloxycarbonyl-tyrosyl)-1,1-dioxo-1,2-dihydro-1λ6-benzo[d]isothiazol-3-one is likely used in the synthesis of more complex molecules, such as peptides or other bioactive compounds, due to its unique structure and protective groups.
The CAS Registry Mumber 6748-43-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 8 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 6748-43: (6*6)+(5*7)+(4*4)+(3*8)+(2*4)+(1*3)=122 122 % 10 = 2 So 6748-43-2 is a valid CAS Registry Number.
