Description

Collman's Reagent is a versatile organometallic compound, specifically disodium tetracarbonylferrate, widely recognized for its role as a nucleophilic carbonylating agent. Its primary value lies in its ability to facilitate the efficient transfer of a carbonyl (CO) group under mild conditions, enabling the synthesis of aldehydes, ketones, and other complex organic molecules. This reagent is essential for researchers and process chemists in the pharmaceutical, agrochemical, and fine chemical industries, where it is used for the construction of key molecular frameworks in active ingredient development.

Application

• Pharmaceutical Synthesis: Key intermediate in the production of complex drug molecules, particularly for carbonyl insertion reactions.
• Fine Chemical Manufacturing: Used in the synthesis of specialty aldehydes, ketones, and carboxylic acid derivatives.
• Agrochemical Research: Employed in the development of novel pesticides and herbicides through carbonylative coupling steps.
• Academic & Industrial R&D: A fundamental tool in organometallic chemistry and methodology development for carbonylation reactions.
• Catalyst Precursor: Serves as a source of iron carbonyl fragments in the preparation of homogeneous catalysts.

Quality Control

Our Collman's Reagent is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Each lot is analyzed to confirm identity, purity, and stability. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by titration), residual solvent content, and moisture level is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Due to its sensitivity to moisture and oxygen, the reagent should be handled in a glovebox or using standard Schlenk line techniques. Long-term storage at temperatures between 2°C and 8°C is recommended to maintain stability.
