Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide Certificates of Analysis (COA) with each batch, detailing purity and key analytical parameters. Quality is assured through modern analytical techniques including HPLC, GC, NMR, and IR spectroscopy. For custom synthesis or specific purity requirements, please contact our technical team to discuss your project needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C/59-77°F). Due to its sensitivity, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, and open flame.
