Quality Control

Our 1-Chloromethyl-4-Methylnaphthalene is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request. We adhere to cGMP guidelines where applicable to meet the stringent requirements of our global clientele in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
