For professionals in the pharmaceutical and fine chemical industries, the decision to buy N-Benzyloxycarbonyl-L-valine (CAS 1149-26-4) is a strategic one, directly impacting the success of complex synthesis projects. This protected amino acid derivative, also known as Z-L-Valine or Cbz-Val-OH, is a crucial building block, demanding high standards of purity and consistency. Understanding where and how to procure this intermediate is key to achieving optimal results.

When you decide to buy N-Benzyloxycarbonyl-L-valine, the first priority should be quality assurance. Look for suppliers who can provide detailed specifications, including purity levels typically confirmed by HPLC analysis (e.g., ≥98%). The presence of the benzyloxycarbonyl (Cbz) group on L-valine makes it an ideal reagent for peptide synthesis and as an intermediate in the creation of various pharmaceuticals. A reputable manufacturer will ensure that their product meets stringent quality standards, such as USP, BP, or FCC, depending on the intended application. Always request a Certificate of Analysis (CoA) to confirm batch-specific quality parameters.

Consider the source of your N-Benzyloxycarbonyl-L-valine. Manufacturers in China are often significant global suppliers, offering competitive pricing. However, it is essential to perform due diligence. Look for suppliers with a strong online presence, clear contact information, and positive customer reviews. Direct inquiries to manufacturers can often yield better prices and more direct communication regarding specifications and delivery schedules. When you buy Z-L-Valine in bulk, establishing a direct relationship with a manufacturer can lead to better pricing and a more secure supply chain.

The pricing of N-Benzyloxycarbonyl-L-valine can fluctuate based on market demand, purity, and order volume. It is advisable to obtain quotes from multiple suppliers to compare prices and terms. Factors to consider include the price per kilogram, minimum order quantities, and shipping costs. While cost is important, it should not be the sole determining factor. Balancing competitive pricing with guaranteed quality and reliable delivery is crucial for long-term success.

In summary, making an informed decision when you buy N-Benzyloxycarbonyl-L-valine requires a focus on quality, purity, and supplier reliability. By carefully evaluating specifications, sourcing from reputable manufacturers, and comparing pricing and terms, you can ensure you acquire a high-quality intermediate that supports the success of your pharmaceutical and fine chemical synthesis endeavors.
