Overview
5-Chloro-2'-deoxyuridine is a modified nucleoside that serves as an analog of thymidine, a natural component of DNA. The substitution of a chlorine atom at the 5-position of the pyrimidine ring distinguishes it from thymidine and confers unique biochemical properties. This compound is widely used in research to study viral replication and DNA synthesis inhibition. Developed as part of nucleoside analog research, 5-Chloro-2'-deoxyuridine has shown potential in antiviral applications. Its mechanism involves incorporation into viral DNA, leading to chain termination or mutagenesis. Researchers value its specificity and efficacy in laboratory settings.
Physical and Chemical Properties
5-Chloro-2'-deoxyuridine is a white to off-white crystalline powder with a molecular weight of 262.65 g/mol. It is soluble in water, DMSO, and methanol, making it suitable for various experimental conditions. The compound exhibits a melting point range of 190-195°C, indicating moderate thermal stability. The presence of the chlorine atom enhances its reactivity and interaction with biological molecules. This modification also affects its solubility and stability under different pH conditions. Researchers should note that the compound may degrade under prolonged exposure to light or elevated temperatures.
Main Applications
The primary application of 5-Chloro-2'-deoxyuridine is in biochemical and virological research. It is used to investigate the mechanisms of DNA synthesis inhibition, particularly in viruses such as herpes simplex and vaccinia. The compound's ability to mimic thymidine allows it to interfere with viral replication processes. Additionally, this nucleoside analog is employed in studies exploring cell proliferation and DNA repair mechanisms. Its antiviral properties make it a candidate for developing therapeutic agents, though clinical use remains limited to experimental settings.
Safety and Storage
5-Chloro-2'-deoxyuridine requires careful handling due to its biological activity. Laboratory personnel should use appropriate personal protective equipment (PPE), including gloves and lab coats, to minimize exposure. Avoid inhalation or ingestion, as the compound may have unintended physiological effects. For long-term storage, the compound should be kept at -20°C in a dry, dark environment to prevent degradation. Containers should be tightly sealed and labeled with relevant hazard information. Disposal should comply with local regulations for chemical waste.
B2B Procurement Guide
When procuring 5-Chloro-2'-deoxyuridine, B2B buyers should prioritize suppliers that provide detailed product specifications and a Certificate of Analysis (COA). The COA ensures the compound's purity and authenticity, which are critical for research accuracy. Buyers should also consider the supplier's reputation, packaging options, and shipping conditions to ensure the product arrives in optimal condition. Bulk purchases may offer cost savings, but storage capacity and shelf life should be evaluated. Comparing prices from multiple suppliers can help secure competitive rates.
