The chemical compound "(1R)-1-[1-(2,4-dinitro-phenyl)-1H-pyrazol-3-yl]-O2,O3-isopropylidene-O1-methanesulfonyl-D-arabinitol" is a complex organic molecule with a unique structure. It features a chiral center at the 1-position, indicated by the "1R" notation, which specifies the configuration of the molecule. The compound contains a pyrazole ring, which is substituted with a 2,4-dinitrophenyl group, providing it with potential reactivity and stability characteristics. The isopropylidene group at the O2 and O3 positions suggests a protecting group that can be used in organic synthesis to prevent unwanted reactions at those hydroxyl groups. Additionally, the methanesulfonyl group at the O1 position is another protecting group, which can be used to control the reactivity of the molecule. (1R)-1-[1-(2,4-dinitro-phenyl)-1H-pyrazol-3-yl]-O2,O3-isopropylidene-O1-methanesulfonyl-D-arabinitol is likely used in advanced organic synthesis, particularly in the preparation of complex molecules where precise control over the reactivity of functional groups is required.
The CAS Registry Mumber 71086-79-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,8 and 6 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 71086-79: (7*7)+(6*1)+(5*0)+(4*8)+(3*6)+(2*7)+(1*9)=128 128 % 10 = 8 So 71086-79-8 is a valid CAS Registry Number.
