129731-10-8

Vorozole is a potent and selective aromatase inhibitor, and its 18F-labeled analogues, such as [18F]FVOZ and [18F]FVOO, have been developed as PET tracers for imaging aromatase activity in the brain. These tracers demonstrate high radiochemical yields, specific binding in aromatase-rich brain regions, and metabolic stability, with [18F]FVOZ showing superior plasma stability compared to [18F]FVOO. The one-step synthesis method offers a reproducible and automatable approach for producing these tracers, supporting their potential use in clinical and research settings for studying aromatase-related processes.

129731-10-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129731-10-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,3 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129731-10:
(8*1)+(7*2)+(6*9)+(5*7)+(4*3)+(3*1)+(2*1)+(1*0)=128
128 % 10 = 8
So 129731-10-8 is a valid CAS Registry Number.

Development summary towards a manufacturable process for R 83842 [(S)-6-[(4-chlorophenyl) (1H-1,2,4-triazol-1-yl)methyl]-1-methyl-1H-benzotriazole]

, p. 162 - 166 (2013/09/07)

A scalable process to produce enantiomeric R 83842, (S)-6-[(4-chlorophenyl)(1H-1,2,4-triazol-1-yl)methyl]-1-methyl-1H-benzotriazole, is developed and described as a lecture * transcript. Cheap and safe reagents have been used. A typical procedure for oxidative destruction of aqueous cyanide waste, and stability data on N-acetyl hydrazine are provided. Special focus is on cost analysis as an important tool in developing performant synthetic methods. The method consists of preparing a chiral monosubstituted hydrazine which is ring closed to the chiral 1-alkylated 1,2,4-triazole title compound.
