(1S)-1-(7-amino-2-isopropyl-2H-pyrazolo[4,3-d]pyrimidin-3-yl)-D-1,4-anhydro-ribitol is a complex organic compound with a unique chemical structure. It features a pyrazolo[4,3-d]pyrimidin-3-yl moiety, which is a heterocyclic ring system with a pyrazole and pyrimidine fused together. The compound also contains an isopropyl group, which is a three-carbon alkyl group derived from propane, attached to the pyrazolo[4,3-d]pyrimidin-3-yl ring. Additionally, it has a D-1,4-anhydro-ribitol unit, which is a modified ribitol molecule with the 1,4-anhydro bridge, indicating the absence of hydroxyl groups at these positions. (1S)-1-(7-amino-2-isopropyl-2H-pyrazolo[4,3-d]pyrimidin-3-yl)-D-1,4-anhydro-ribitol is characterized by its chirality, with the (1S) configuration indicating the specific arrangement of atoms around the chiral center. The presence of an amino group at the 7-position of the pyrazolo[4,3-d]pyrimidin-3-yl ring further contributes to its reactivity and potential applications in medicinal chemistry or as a building block for more complex molecules.
The CAS Registry Mumber 67187-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,8 and 7 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 67187-16: (7*6)+(6*7)+(5*1)+(4*8)+(3*7)+(2*1)+(1*6)=150 150 % 10 = 0 So 67187-16-0 is a valid CAS Registry Number.
