23003-29-4 Usage
Uses
Used in Agricultural Industry:
2,4-Dibromo-3-hydroxy-6-picoline is used as a herbicide for controlling broadleaf weeds in crops such as cereals, cotton, and vegetables. It is applied for its effectiveness in blocking essential enzyme systems in plants, leading to their death and thus protecting the growth of desired crops.
Check Digit Verification of cas no
The CAS Registry Mumber 23003-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,0 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23003-29:
(7*2)+(6*3)+(5*0)+(4*0)+(3*3)+(2*2)+(1*9)=54
54 % 10 = 4
So 23003-29-4 is a valid CAS Registry Number.

Efficient regioselective preparation of monobromo and bromoiodo hydroxy pyridines from dibromoderivatives via bromine-lithium exchange

Annular dibromination of hydroxypyridines with NBS in acetonitrile followed by bromine-lithium exchange with RLi and subsequent trapping with H2O or I2 afforded monobromo and bromoiodo derivatives in a completely regioselective way. Iodination of bromo hydroxypyridines with NIS is totally regioselective.
