Quality Control

Our 4-Azido-2,3,5,6-Tetrafluorobenzoic Acid Stp Ester Sodium Salt is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. All products undergo rigorous analytical testing, including HPLC, NMR, and MS, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We adhere to cGMP standards where applicable to support our clients in regulated industries.

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). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Keep away from heat, sparks, and open flame.
