Description

Methylmagnesium Iodide is a highly reactive organometallic compound, specifically a Grignard reagent, widely used for introducing methyl groups in organic synthesis. Its core value lies in its ability to act as a powerful nucleophile and strong base, enabling critical carbon-carbon bond formation reactions essential for building complex molecular architectures. This reagent is indispensable for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors, where precise methyl group transfer is required.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for the methylation of carbonyl compounds (ketones, aldehydes, esters) and epoxides in the production of active pharmaceutical ingredients (APIs).
• Agrochemical Manufacturing: Used in the synthesis of herbicides, fungicides, and plant growth regulators that require methylated structures.
• Fine Chemical Production: Employed in the synthesis of specialty chemicals, flavors, fragrances, and dyes where methyl group installation is a critical step.
• Polymer & Material Science: Serves as an initiator or modifying agent in the synthesis of specialized polymers and advanced organic materials.
• Academic & Industrial R&D: A fundamental tool in exploratory organic chemistry for method development and the construction of novel organic molecules.

Quality Control

Our Methylmagnesium Iodide is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. We provide comprehensive Certificates of Analysis (COA) with each batch, detailing key parameters such as concentration (typically as a solution in diethyl ether or THF), assay, and impurity profiles. Our quality systems are designed to support cGMP manufacturing where applicable, ensuring the material meets the exacting standards required for pharmaceutical and high-value chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and moisture-sensitive nature, this product must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. For solutions, store at recommended temperatures (typically 2-8°C for extended shelf life) and keep away from heat, sparks, open flames, and incompatible materials such as water, acids, and oxidizing agents.
