1256256-45-7 Usage
Uses
Used in Pharmaceutical Industry:
4-(Boc-aMino)-2-fluorobenzeneboronic acid pinacol ester, 96% is used as a key intermediate for the synthesis of 3-Dihydro-1,4-benzodiazepin-2(2H)-ones and 3-Amino-1,3-dihydro-1,4-benzodiazepin-2(2H)-ones. These compounds are important in the development of new drugs and therapeutic agents.
Application Reason:
The synthesis of these benzodiazepine derivatives is facilitated through Pd-catalyzed cross-coupling of imidoyl chlorides with organoboronic acids, which is a widely used method in organic chemistry. This process allows for the creation of a diverse range of compounds with potential applications in the treatment of various medical conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 1256256-45-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,5 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1256256-45:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*5)+(3*6)+(2*4)+(1*5)=157
157 % 10 = 7
So 1256256-45-7 is a valid CAS Registry Number.
