Quality Control

Our 2-Methyl-1-Naphthylmagnesium Bromide is manufactured and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as concentration (typically supplied as a solution in THF or diethyl ether), assay by titration, and impurity profile. We adhere to cGMP principles where applicable, and our quality system is designed to meet the exacting standards of advanced chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this product must be stored under a dry, inert atmosphere (argon or nitrogen) at recommended temperatures, typically between 2°C and 8°C for extended stability. Keep away from moisture, heat, and incompatible materials such as acids, water, and oxidizing agents. Use only in a well-ventilated area with appropriate safety equipment.
