While widely recognized for its fundamental role in RNA and biological systems, Uracil (CAS 66-22-8) also possesses chemical properties that make it a valuable compound in broader chemical applications and as a fine chemical intermediate. For procurement managers and chemists seeking versatile building blocks, understanding Uracil's characteristics can unlock new synthesis pathways and product development opportunities. This article highlights Uracil's utility in the fine chemical sector and provides sourcing guidance.

Uracil, chemically known as 2,4(1H,3H)-pyrimidinedione, is an organic compound characterized by its pyrimidine ring structure substituted with two oxo groups. Its typical appearance is a white to off-white crystalline powder, with a melting point well above 300°C, indicating its thermal stability. Its solubility in hot water and certain alkaline solutions, contrasted with its limited solubility in alcohols and ethers, dictates its handling and reaction conditions in various chemical processes.

As a fine chemical, Uracil serves as a crucial starting material or intermediate in the synthesis of a wide range of organic compounds. Its reactive sites on the pyrimidine ring allow for various chemical modifications, leading to the creation of more complex molecules used in agrochemicals, dyes, and specialty polymers. The pharmaceutical industry, of course, remains a primary consumer, utilizing Uracil in the synthesis of drugs like 5-fluorouracil, a widely used antineoplastic agent, and various antiviral nucleoside analogs. When you buy Uracil for these purposes, ensuring high purity (≥99.0%) is essential to prevent interference with downstream reactions.

Researchers and manufacturers often look to source Uracil from reliable suppliers who can guarantee consistent quality and provide necessary documentation. For those seeking a Uracil supplier in China, there are numerous manufacturers and distributors offering this compound. Key considerations when evaluating suppliers include their adherence to international quality standards (e.g., ISO certification), the availability of comprehensive Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS), and their capacity to provide technical support.

The price of Uracil can fluctuate based on market demand, raw material costs, and order volume. Companies looking to purchase Uracil in bulk will typically find more competitive pricing from direct manufacturers. It is prudent to obtain quotes from several trusted sources to compare not only the price but also the overall service, including lead times, packaging options (commonly 25 kg drums), and shipping reliability.

Beyond its direct use, Uracil's derivatives and its role as a precursor highlight its versatility. For instance, its chemical modification can yield compounds with different solubilities and reactivities, broadening its applicability in materials science and industrial chemistry. A proactive approach to sourcing involves identifying suppliers who can consistently meet evolving requirements and potentially offer custom synthesis services for Uracil derivatives.

In summary, Uracil (CAS 66-22-8) is more than just a biological molecule; it is a valuable fine chemical with significant applications in synthesis. By understanding its chemical properties and partnering with reputable manufacturers and suppliers, businesses can effectively leverage Uracil to develop innovative products and processes.
