Quality Control

Every batch of 4-Anilino-D5-4-Oxobutanoic Acid is produced and tested under strict quality management protocols to ensure high chemical purity and isotopic enrichment. Our quality assurance includes comprehensive analytical characterization using techniques such as NMR, HPLC, and MS. A Certificate of Analysis (COA) detailing purity, isotopic purity (D-enrichment), and specific tests is provided with each shipment to guarantee compliance with your research specifications.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
