5,5'-Isopropyliden-disalicylsaeure-dimethylester, also known as 5,5'-isopropylidene bis(salicylic acid dimethyl ester), is a chemical compound with the molecular formula C16H18O6. It is a white crystalline solid that is derived from the reaction of salicylic acid with acetone and dimethyl sulfate. 5,5'-Isopropyliden-disalicylsaeure-dimethylester is characterized by its symmetrical structure, featuring two salicylic acid units connected through an isopropylidene bridge. It is used as an intermediate in the synthesis of various pharmaceuticals and other organic compounds due to its ability to serve as a precursor for the preparation of complex molecules. The isopropylidene group provides protection for the hydroxyl groups, which can be removed under acidic conditions to regenerate the hydroxyl groups, making it a valuable building block in organic synthesis.

2115-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2115-32-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 2115-32:
(6*2)+(5*1)+(4*1)+(3*5)+(2*3)+(1*2)=44
44 % 10 = 4
So 2115-32-4 is a valid CAS Registry Number.
