Quality Control

Every batch of 7,11,12-Trimethylbenz(A)Anthracene is manufactured and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC-MS, and NMR to ensure identity, purity, and consistency meet the exacting standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 15-25°C. Due to its light-sensitive and easily oxidized nature, prolonged exposure to air and light should be avoided to maintain product integrity.
