50567-35-6

[(2,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl-1H-pyrazol-4-yl)methylamino]methanesulphonic acid is a pyrazole derivative that features a methyl(sulfomethyl)amino group substitution at the C-4 position of the antiipyrine molecule. It is related to metamizole sodium, a compound that was once widely used as a potent analgesic and antipyretic but has since been withdrawn from many markets due to the risk of causing agranulocytosis.

50567-35-6 Usage

Uses

Used in Pharmaceutical Industry:
[(2,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl-1H-pyrazol-4-yl)methylamino]methanesulphonic acid is used as an active pharmaceutical ingredient for the development of medications targeting pain relief and fever reduction. Its structure and properties suggest potential applications similar to those of metamizole sodium, although it is important to consider the safety concerns associated with agranulocytosis when developing new formulations or therapies.

Check Digit Verification of cas no

The CAS Registry Mumber 50567-35-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,5,6 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50567-35:
(7*5)+(6*0)+(5*5)+(4*6)+(3*7)+(2*3)+(1*5)=116
116 % 10 = 6
So 50567-35-6 is a valid CAS Registry Number.
