Quality Control

Our production of Butanoic Acid, 2-Chloro-3-Oxo-, Methyl Ester, Radical Ion(1+) adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity for research applications. While produced as a high-grade research chemical, we support our clients with comprehensive analytical data. Certificates of Analysis (COA) detailing purity, identity confirmation, and impurity profiles are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

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