Quality Control

Our 3-Methoxy-10H-Phenothiazine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances, IR for identification, and residual solvent analysis. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in darkness. For long-term storage, consider an inert atmosphere to prevent potential oxidation.
