3,4:5,6-Di-O-isopropylidene-D-glucose diethyl mercaptal is a complex organic compound with the molecular formula C16H30O5S2. It is derived from D-glucose, a monosaccharide, by protecting the hydroxyl groups at positions 3, 4, 5, and 6 with isopropylidene groups and forming a mercaptal with diethyl mercaptan. 3,4:5,6-Di-O-isopropylidene-D-glucose diethyl mercaptal is often used in organic synthesis and as a protecting group in carbohydrate chemistry. The isopropylidene groups prevent unwanted reactions at these positions, while the diethyl mercaptal group can be used to introduce sulfur-containing functional groups or as a protecting group for the aldehyde functionality. The compound is typically synthesized through a multi-step process involving the protection of the hydroxyl groups and subsequent reaction with diethyl mercaptan. It is an important intermediate in the preparation of various glycosides and other complex carbohydrate derivatives.

4435-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4435-02-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 4435-02:
(6*4)+(5*4)+(4*3)+(3*5)+(2*0)+(1*2)=73
73 % 10 = 3
So 4435-02-3 is a valid CAS Registry Number.
