2,3-O-isopropylidene-L-threose diethyl mercaptal is a complex organic compound with the molecular formula C11H22O4S. It is a derivative of L-threose, a naturally occurring sugar, where the 2nd and 3rd hydroxyl groups are protected with an isopropylidene group, and the aldehyde group is converted to a mercaptal by reaction with diethyl sulfide. 2,3-O-isopropylidene-L-threose diethyl mercaptal is used in organic synthesis, particularly in the preparation of complex carbohydrates and as a protecting group in carbohydrate chemistry. The isopropylidene group provides stability and prevents unwanted side reactions, while the diethyl mercaptal group can be selectively removed under mild conditions, making it a valuable intermediate in the synthesis of various biologically active compounds.

4258-08-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4258-08-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.Calculate Digit Verification of CAS Registry Number 4258-08:
(6*4)+(5*2)+(4*5)+(3*8)+(2*0)+(1*8)=86
86 % 10 = 6
So 4258-08-6 is a valid CAS Registry Number.
