Quality Control

Our production of 1-Naphthalenethiol,4-Methoxy-(7Ci,9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and NMR/IR for structural confirmation, to ensure consistency and meet precise customer specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be kept sealed and only opened in an inert environment to maintain product integrity.
