Quality Control

Every batch of 2-Chloro-3-Formylisonicotinic Acid is manufactured under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and IR spectroscopy to ensure identity, purity, and consistency meet the high standards required for research and production. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee full traceability and compliance with your 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 (moisture-sensitive) nature, the container must be kept tightly sealed under dry conditions. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
