Quality Control

Every batch of Chlorimuron Impurity 1 is produced and analyzed under strict quality management protocols. We provide comprehensive analytical data to support its use as a reference material. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity (typically ≥95% by HPLC), and impurity profile. Our quality systems are designed to meet the stringent requirements of GMP and ISO standards for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; ensure the container is kept sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
