4-Pyrimidinecarboxylicacid,5-bromo - Introduction

Acid is an organic compound with the chemical formula C5H3BrN2O2. The following is a description of the properties, uses, preparation and safety information of the compound:

Nature:
-Appearance: acid is a white solid.
-Melting point: about 185-187 ℃.
-Solubility: Insoluble in water, but soluble in organic solvents such as alcohols, ethers and ketones.

Use:
-must acid is often used as a starting material and intermediate in organic synthesis.
-It can be used to synthesize pyrimidine compounds, such as drugs, pesticides, dyes and functional materials.
-The compound can also be used as a reference material for nuclear magnetic resonance (NMR).

Preparation Method:
-the acid can be synthesized by the following steps:
1.5-bromo -2, 4-dimethylpyrimidine is reacted with zinc dinitrate to obtain 5-bromo -2, 4-dimethylpyrimidine nitrite.
2. The nitrite ester was hydrolyzed and acidified to obtain 5-bromo-2, 4-dimethylpyrimidine nitric acid.
3. Reduction of nitric acid to amine and acidolysis to give 5-bromo-2, 4-dimethylpyrimidine.
4. Finally, 5-bromo -2, 4-dimethylpyrimidine and chlorine oxide are reacted to obtain acid.

Safety Information:
-the acid may be stable and harmless under normal circumstances, but appropriate laboratory safety procedures should be followed.
-When using or handling, avoid direct contact with skin, eyes and respiratory tract, and ensure that the operation is carried out in a well-ventilated place.
-If inhaled or ingested, seek medical attention immediately.
-Detailed safety information and hazard assessment should refer to the safety data sheet (SDS) of the chemical.
