Quality Control

Our 2-Chloro-4-Methylnaphthalene is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in darkness.
