Thymidine, identified by its CAS number 50-89-5, is a compound of immense importance in molecular biology and pharmaceutical development. As a pyrimidine deoxynucleoside, it forms one of the fundamental nucleobases of DNA, pairing specifically with deoxyadenosine. Understanding its chemical properties and applications is crucial for researchers and procurement professionals in the pharmaceutical sector.

Chemically, Thymidine is designated as 1-(2-deoxy-β-D-ribofuranosyl)-5-methylpyrimidine-2,4(1H,3H)-dione. Its molecular formula is C10H14N2O5, with a molecular weight of 242.23. The compound typically appears as a white crystalline powder, a characteristic that signifies its purity and suitability for demanding applications. This specific appearance is a key indicator for quality control when sourcing from a chemical manufacturer.

The applications of Thymidine are diverse and critical. Primarily, it serves as a vital pharmaceutical intermediate. Its structure makes it an essential starting material for synthesizing a range of therapeutic agents, including those used to combat HIV/AIDS, various cancers, and other viral infections. For instance, it is a precursor to potent anti-tumor and antiviral drugs. Its role in DNA synthesis means it is also invaluable in cell biology research for synchronizing cells in the S phase, aiding in studies of DNA replication and repair.

When sourcing Thymidine for research or production, quality and consistency are paramount. Pharmaceutical grade Thymidine should meet stringent standards such as USP, BP, and EP. Buyers looking to buy this compound often seek suppliers in regions with robust chemical manufacturing capabilities, such as China. A reliable supplier will provide detailed product specifications, including purity assays, melting points (typically 186-188°C), and solubility data.

For businesses involved in drug discovery or manufacturing, understanding the sourcing landscape is key. Manufacturers offering Thymidine at competitive prices often provide bulk ordering options, with minimums as low as 1kg, scaling up to 25kg drums or more. Direct price inquiry is the most effective way to ascertain current market rates and secure favorable terms. The availability of reliable documentation, such as Certificates of Analysis (COA) and Technical Data Sheets (TDS), is also a hallmark of a trustworthy chemical supplier.

In essence, Thymidine (CAS 50-89-5) is more than just a chemical compound; it is a foundational element in medical advancement. Its well-defined chemical properties and critical applications in pharmaceutical synthesis and research underscore its importance. By partnering with experienced Chinese manufacturers and suppliers, organizations can ensure access to high-quality Thymidine to drive their innovative projects forward.
