For procurement specialists and research scientists, selecting the right chemical intermediates is a critical step in ensuring the success of their projects. Boc-D-Glutamic Acid 5-Benzyl Ester (CAS: 35793-73-8) is a highly sought-after protected amino acid, vital for peptide synthesis, drug development, and various organic chemistry applications. However, making an informed purchase requires a clear understanding of its specifications and what to look for when sourcing from manufacturers.

As a leading supplier and manufacturer of fine chemicals, NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of detailed product specifications. These details are not just for documentation; they are crucial indicators of product quality, suitability for specific applications, and the reliability of the supplier. When you plan to buy Boc-D-Glutamic Acid 5-Benzyl Ester, pay close attention to the following:

Key Specifications to Consider:

  • Purity: This is arguably the most important specification. For Boc-D-Glutamic Acid 5-Benzyl Ester, purity levels of ≥97% are commonly sought, especially for pharmaceutical applications. Higher purity often translates to cleaner reactions, better yields, and reduced downstream purification efforts. Always request a Certificate of Analysis (CoA) detailing the purity and the analytical method used (e.g., HPLC).
  • Appearance: The typical appearance for Boc-D-Glutamic Acid 5-Benzyl Ester is a white powder. Any deviation from this, such as discoloration or clumping, might indicate improper storage, degradation, or contamination. As a manufacturer, we ensure our product maintains its specified appearance.
  • CAS Number: The Chemical Abstracts Service (CAS) registry number, 35793-73-8, is a unique identifier for this compound. Always verify the CAS number to ensure you are procuring the correct chemical entity.
  • Molecular Formula and Weight: C17H23NO6 and a molecular weight of approximately 337.37 g/mol are standard identifiers. These are fundamental for stoichiometric calculations in synthesis.
  • Storage Conditions: Proper storage is key to maintaining the integrity of Boc-D-Glutamic Acid 5-Benzyl Ester. Typically, it is recommended to store it sealed in a dry environment at 2-8°C. Manufacturers who adhere to these conditions demonstrate good practice.
  • Chiral Purity: Given its use in synthesizing biologically active molecules, the specific stereochemistry (D-configuration) is critical. Buyers should inquire about chiral purity, often specified as a high percentage, and the methods used for its determination.
