Description

Iodomethane is a versatile alkylating agent and a fundamental building block in organic synthesis. Its high reactivity makes it a critical reagent for introducing methyl groups into target molecules, enabling the production of a wide range of advanced intermediates and final products. This compound is essential for research and manufacturing in the pharmaceutical, agrochemical, and fine chemical industries. For precise sourcing, the identifier Iodomethane CAS NO 16519-98-5 is commonly used.

Application

• Pharmaceutical Synthesis: Key intermediate in the production of active pharmaceutical ingredients (APIs), particularly for methylation reactions in drug discovery and development.
• Agrochemical Manufacturing: Used in the synthesis of pesticides, herbicides, and fungicides where methyl group incorporation is required.
• Fine Chemical Production: Serves as a methylating agent in the synthesis of specialty chemicals, dyes, and flavor/fragrance compounds.
• Laboratory Research: A standard reagent in academic and industrial R&D labs for organic transformations, including nucleophilic substitution and coupling reactions.
• Material Science: Employed in surface modification and the synthesis of organic electronic materials.
• Analytical Chemistry: Used as a derivatization agent in gas chromatography and other analytical techniques.

Quality Control

Our Iodomethane is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. Our quality protocols are designed to meet the exacting standards required for synthetic applications across pharmaceutical and industrial sectors.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
