5-Chlorouracil(CAS: 1820-81-1)

5-Chlorouracil is a chlorinated pyrimidine derivative with the chemical formula C4H3ClN2O2. It appears as a white crystalline powder and is known for its stability under normal conditions. This compound is widely used as a building block in pharmaceutical research, particularly in the development of antiviral and anticancer drugs due to its structural similarity to uracil.

5-Chlorouracil serves as a key intermediate in the synthesis of various pharmaceutical compounds, including antiviral agents and chemotherapy drugs. It is also utilized in research for studying nucleic acid metabolism and in industrial applications for producing agrochemicals and dyes. Its versatility makes it relevant in drug development and chemical synthesis processes.

5-Chlorouracil is classified as a hazardous chemical and requires careful handling. It may cause skin and eye irritation, and its vapors can be harmful if inhaled. Safety standards emphasize the use of personal protective equipment (PPE) and proper ventilation. Handling should follow OSHA and EPA guidelines to minimize exposure risks in laboratories and industrial settings.

5-Chlorouracil should be stored in a cool, dry place away from light, ideally at 2-8°C. It requires airtight containers to prevent moisture absorption and maintain stability. Avoid exposure to incompatible substances like strong oxidizers. Proper storage ensures safety and prolongs the compound's shelf life in research and industrial applications.
