The acquisition of high-quality chemical intermediates is a critical step in the successful execution of research and development projects. L-Glutamic acid dibenzyl ester 4-toluenesulfonate (CAS 2791-84-6) is a compound that holds significant importance across several scientific disciplines, primarily in peptide synthesis and pharmaceutical intermediate manufacturing. This guide aims to assist buyers in sourcing this compound effectively, ensuring they obtain the quality and reliability needed for their applications.

When looking to buy L-Glutamic acid dibenzyl ester 4-toluenesulfonate, understanding its primary uses is the first step. Its role as a protecting group for carboxylic acids in peptide synthesis is paramount. The dibenzyl ester groups offer a stable protection that can be selectively removed, contributing to the efficient construction of complex peptide chains. For pharmaceutical development, it serves as a key intermediate in the synthesis of neuroprotective agents and other drug candidates, leveraging the biological significance of glutamic acid.

The quality of L-Glutamic acid dibenzyl ester 4-toluenesulfonate is often defined by its purity, typically specified by HPLC analysis. Buyers should look for products with high purity levels (e.g., ≥ 98% or ≥ 99%) to ensure predictable reaction outcomes and minimize the introduction of unwanted impurities into their synthesis pathways. The physical form, usually a white powder, and appropriate storage conditions (e.g., at room temperature in a dry, dark place) are also important considerations for maintaining product integrity.

Identifying reliable suppliers is crucial for consistent procurement. Many companies specialize as a chemical intermediate supplier, offering a range of amino acid derivatives and related compounds. These suppliers often provide detailed product specifications, safety data sheets (SDS), and certificates of analysis (CoA) upon request. When sourcing from China, for instance, verifying the supplier's reputation, certifications (like ISO), and commitment to quality control is advisable. A well-established organic synthesis protecting group supplier will likely have robust quality assurance processes in place.

The pricing of L-Glutamic acid dibenzyl ester 4-toluenesulfonate can vary based on quantity, purity, and supplier. Bulk purchases generally offer cost savings, making it advantageous for companies with ongoing production needs. Buyers should also consider factors such as lead times, shipping options, and customer support when making their purchasing decisions.

In summary, sourcing high-quality L-Glutamic acid dibenzyl ester 4-toluenesulfonate involves understanding its applications, prioritizing product purity, and selecting a trustworthy supplier. By paying attention to these details, researchers and manufacturers can secure the essential materials needed to drive their projects forward successfully.
