The chemical compound "(1R)-1-(2,4-bis-benzyloxy-pyrimidin-5-yl)-O2,O3;O4,O5-diisopropylidene-D-xylitol" is a complex organic molecule with a unique structure. It features a pyrimidin-5-yl group at the 1-position, which is substituted with two benzyloxy groups at the 2 and 4 positions. The D-xylitol moiety is protected with diisopropylidene groups at the 2, 3; 4, 5 positions, which are commonly used in organic synthesis to protect hydroxyl groups from unwanted reactions. (1R)-1-(2,4-bis-benzyloxy-pyrimidin-5-yl)-O2,O3;O4,O5-diisopropylidene-D-xylitol is likely used in the synthesis of more complex molecules, such as pharmaceuticals or other bioactive compounds, where the pyrimidine and xylitol moieties could be key structural elements. The specific stereochemistry at the 1-position (1R) and the protection of the hydroxyl groups suggest that (1R)-1-(2,4-bis-benzyloxy-pyrimidin-5-yl)-O2,O3;O4,O5-diisopropylidene-D-xylitol is a精细中间体 in a multi-step synthesis process, designed to be further modified or deprotected to yield the final desired product.
The CAS Registry Mumber 13039-96-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,3 and 9 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 13039-96: (7*1)+(6*3)+(5*0)+(4*3)+(3*9)+(2*9)+(1*6)=88 88 % 10 = 8 So 13039-96-8 is a valid CAS Registry Number.
