4-Hydroxy-3-methylbenzenesulfonyl fluoride, also known as 4-hydroxy-3-methylbenzenesulfonic acid fluoride or tosyl fluoride, is an organic compound with the chemical formula C7H7FO3S. It is a colorless crystalline solid that is soluble in organic solvents. Tosyl fluoride is a valuable reagent in organic synthesis, particularly in the formation of carbon-fluorine bonds and as a protecting group in peptide synthesis. It is used to convert alcohols into alkyl fluorides and to introduce a tosyl group (tosyl = 4-HO-3-Me-benzenesulfonyl) into organic molecules. The compound is also known for its use in the preparation of various pharmaceuticals and agrochemicals. Due to its reactivity and potential hazards, it is important to handle tosyl fluoride with care, following appropriate safety protocols.

328-85-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 328-85-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 328-85:
(5*3)+(4*2)+(3*8)+(2*8)+(1*5)=68
68 % 10 = 8
So 328-85-8 is a valid CAS Registry Number.
