In the realm of fine chemicals, particularly those destined for pharmaceutical and cosmetic applications, precision in purity and adherence to specifications are non-negotiable. 3-Nitro-L-phenylalanine (CAS 19883-74-0) is a prime example of such a critical intermediate. Typically presented as a white powder, its utility is intrinsically linked to its quality. For B2B buyers, understanding these specifications and sourcing from a manufacturer that consistently meets them is vital for successful product development and manufacturing.

The chemical formula for 3-Nitro-L-phenylalanine is C9H10N2O4, with a molecular weight of 210.1867. A standard specification that buyers look for is a purity level of 98%. This high purity ensures that the compound functions effectively as a building block in complex synthetic pathways, minimizing the risk of unwanted side reactions or impurities in the final product. When you search to 'buy 3-Nitro-L-phenylalanine', always prioritize suppliers who clearly state and can verify their purity levels.

Beyond purity, other specifications may be relevant depending on the intended application. These can include particle size distribution, moisture content, and the absence of specific trace metals or organic contaminants. A reliable '3-Nitro-L-phenylalanine supplier' will provide a comprehensive Certificate of Analysis (CoA) with each batch, detailing these critical parameters. This documentation is fundamental for quality assurance and regulatory compliance within the pharmaceutical and cosmetic industries.

For procurement professionals, identifying manufacturers with robust quality management systems is key. Companies specializing in fine chemical manufacturing in China often have the infrastructure and expertise to produce and certify chemicals to high standards. When evaluating potential sources, inquire about their analytical capabilities and compliance certifications. This diligence helps ensure that the 'chemical price 19883-74-0' you receive reflects a product that meets your exact requirements.

The journey from raw material to finished product often involves multiple synthesis steps, making the quality of each intermediate, like 3-Nitro-L-phenylalanine, foundational. By prioritizing detailed specifications and partnering with reputable manufacturers, businesses can secure the high-quality chemical intermediates necessary for their success. Consider reaching out to established suppliers for detailed product information and a formal quote.
