23003-29-4 Usage
General Description
2,4-Dibromo-3-hydroxy-6-picoline, also known as bromoxynil, is a synthetic compound that is commonly used as an herbicide to control broadleaf weeds in crops such as cereals, cotton, and vegetables. It works by blocking the essential enzyme system in plants, ultimately leading to their death. Bromoxynil is a highly effective and fast-acting herbicide, with low toxicity to mammals, birds, and aquatic organisms. However, it can be toxic to some non-target plants and may have some negative impacts on the environment. Therefore, it is important to use this chemical with caution and follow recommended application guidelines to minimize potential risks.
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.
