((2S,4S,6S)-4-Hydroxy-2-methoxy-6-methyl-tetrahydro-pyran-2-yl)-acetic acid tert-butyl ester is a complex organic compound with the molecular formula C13H22O5. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the 2, 4, and 6 positions all being in the S configuration. ((2S,4S,6S)-4-Hydroxy-2-methoxy-6-methyl-tetrahydro-pyran-2-yl)-acetic acid tert-butyl ester features a tetrahydro-pyran ring, which is a type of cyclic ether, and it includes a hydroxyl group, a methoxy group, and a methyl group. The acetic acid part of the molecule is esterified with a tert-butyl group, which is a bulky, sterically hindered alkyl group. This esterification protects the carboxylic acid group, which can be important in chemical synthesis to prevent unwanted reactions at that site. The compound is likely used in the synthesis of more complex molecules, possibly in the pharmaceutical or chemical industry, due to its unique structural features and reactivity.
The CAS Registry Mumber 88559-61-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,5,5 and 9 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 88559-61: (7*8)+(6*8)+(5*5)+(4*5)+(3*9)+(2*6)+(1*1)=189 189 % 10 = 9 So 88559-61-9 is a valid CAS Registry Number.
