Quality Control

We maintain a strict quality management system aligned with cGMP principles for fine chemicals. Every batch of 2-Quinoxalinepropanoicacid,α-Amino-,Ethylester(9Ci) is subjected to rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to ensure full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials.
