74647-99-7 Usage
Uses
Used in Pharmaceutical Industry:
[1,1'-Biphenyl]-4-acetic acid, α-methyl-, methyl ester is used as a key intermediate in the synthesis of Biprofen, which is a metabolite of Isopropylbiphenyl. Isopropylbiphenyl is a COX-2 selective inhibitor, a type of nonsteroidal anti-inflammatory drug (NSAID) that selectively targets the COX-2 enzyme to reduce inflammation and pain.
Additionally, [1,1'-Biphenyl]-4-acetic acid, α-methyl-, methyl ester is recognized as an impurity of Flurbiprofen (F598700), another NSAID that also functions as a COX-2 selective inhibitor. Its presence as an impurity highlights the importance of monitoring and controlling the synthesis process to ensure the purity and efficacy of the final pharmaceutical product.
Check Digit Verification of cas no
The CAS Registry Mumber 74647-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,4 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74647-99:
(7*7)+(6*4)+(5*6)+(4*4)+(3*7)+(2*9)+(1*9)=167
167 % 10 = 7
So 74647-99-7 is a valid CAS Registry Number.
