Chlorosulfuric acid, butyl ester, also known as butyl chlorosulfate, is an organosulfur compound with the chemical formula C4H9ClO3S. It is a colorless, oily liquid that is soluble in organic solvents and has a pungent odor. Chlorosulfuric acid, butyl ester is formed by the reaction of butanol with chlorosulfuric acid, resulting in the formation of an ester linkage. Butyl chlorosulfate is primarily used as a reagent in organic synthesis, particularly in the preparation of various esters and amides. It is also employed as a chlorinating and sulfating agent in the production of pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity and potential hazards, it is essential to handle butyl chlorosulfate with caution, using appropriate safety measures and protective equipment.

763-23-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 763-23-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.Calculate Digit Verification of CAS Registry Number 763-23:
(5*7)+(4*6)+(3*3)+(2*2)+(1*3)=75
75 % 10 = 5
So 763-23-5 is a valid CAS Registry Number.
