For professionals engaged in drug discovery, medicinal chemistry, and biochemical research, the selection and procurement of high-quality chemical intermediates are critical for project success. N-Boc-L-Tryptophan, a key protected amino acid with CAS number 13139-14-5, is one such compound that finds extensive use in these fields. This article aims to guide procurement managers and research scientists in identifying reliable sources and understanding the key considerations when purchasing this vital intermediate.

N-Boc-L-Tryptophan serves as an indispensable building block in organic synthesis, particularly in the construction of peptides and peptidomimetics. Its Boc protecting group offers convenient selective deprotection, allowing for controlled chain elongation. When seeking to buy N-Boc-L-Tryptophan, several factors should be prioritized: purity, consistency, and the reputation of the manufacturer or supplier. Given its application in sensitive research and potential pharmaceutical development, impurities can significantly impact reaction outcomes and downstream analysis.

Many R&D professionals look to China for cost-effective sourcing of chemical intermediates. When evaluating Chinese manufacturers and suppliers for N-Boc-L-Tryptophan, it is crucial to look for companies that emphasize quality control and provide detailed product specifications, including certificates of analysis (CoA) that confirm purity (often stated as ≥97% or ≥98% HPLC) and other critical parameters. Understanding the CAS number 13139-14-5 is the first step in ensuring you are sourcing the correct chemical entity.

Furthermore, inquire about packaging options, storage recommendations (typically cool, dark, and dry conditions), and the supplier's ability to provide samples for initial evaluation. Establishing a relationship with a consistent supplier who can offer competitive pricing for bulk purchases is also a strategic advantage. Whether your project requires gram quantities for initial screening or kilogram quantities for scale-up synthesis, a reliable manufacturer in China can meet these demands.
