The product, Factory Supply cytidine cas 65-46-3 With Best Price, is a cytidine compound. Cytidine, with the CAS number 65 - 46 - 3, has a molecular formula of C₉H₁₃N₃O₅ and a molecular weight of approximately 243.22 g/mol. It is a white to off - white crystalline powder. This product is factory - supplied, which ensures a stable source and high quality at a competitive price. The purity of our cytidine product can usually reach over 98%, which is determined by high - performance liquid chromatography (HPLC). It is soluble in water to some extent, and its solubility can vary depending on the temperature and pH conditions. The melting point of cytidine is around 210 - 212 °C.
Cytidine has a wide range of applications in different fields. In the pharmaceutical field, it is an important intermediate for the synthesis of various drugs. For example, it can be used in the synthesis of antiviral drugs. Some research has shown that certain derivatives of cytidine have inhibitory effects on specific viruses. In the field of biotechnology, cytidine is used in cell culture media. It provides necessary nutrients for cell growth and metabolism, helping to maintain the normal physiological state of cells. In the food industry, cytidine can be added to some functional foods as a nutritional supplement. It may contribute to improving human immune function and nerve function.
When using cytidine, it is necessary to follow strict operating procedures. In the laboratory, for the preparation of solutions, first, weigh an appropriate amount of cytidine accurately according to the experimental requirements. Then, add it to a suitable solvent slowly under stirring conditions. If it is used for cell culture, the cytidine should be sterilized first, usually by filtration through a 0.22 - μm filter membrane. The concentration of cytidine in the culture medium should be carefully controlled. Generally, the recommended concentration range is 0.1 - 1 mM, but this may need to be adjusted according to the specific cell type and experimental purpose. In drug synthesis, cytidine should be stored in a dry and cool place before use to prevent degradation. During the synthesis process, strict temperature, pH, and reaction time control are required according to the specific reaction steps.
Case 1: In a cell culture experiment, a research team was culturing neural stem cells. They added cytidine to the culture medium at a concentration of 0.5 mM. After a week of culture, they found that the neural stem cells showed better proliferation ability compared to the control group without cytidine addition. The cells also had a higher differentiation rate into neurons, which indicated that cytidine played an important role in promoting the growth and differentiation of neural stem cells.
Case 2: A pharmaceutical company was synthesizing a new antiviral drug. They used cytidine as a key intermediate. By strictly controlling the reaction conditions, such as reacting at a temperature of 50 °C for 5 hours under alkaline conditions, they successfully synthesized the target drug with a high yield. The drug showed good antiviral activity in subsequent in - vitro and in - vivo tests.
