Description

(1-Ethylbutyl)Magnesium Bromide is a highly reactive organomagnesium compound, commonly known as a Grignard reagent. Its primary value lies in its ability to act as a powerful nucleophile and strong base in critical carbon-carbon bond-forming reactions for complex organic synthesis. This makes it an essential intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors. The compound, CAS NO 68941-76-4, is particularly valued for introducing the branched (1-ethylbutyl) group into target molecules.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), especially for compounds requiring specific alkyl chain architectures.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and pesticides where the (1-ethylbutyl) moiety imparts desired biological activity.
• Fine Chemical & Specialty Chemical Production: Employed in the manufacture of flavors, fragrances, and performance chemicals.
• Polymer & Material Science: Serves as an initiator or modifying agent in the development of specialized polymers and advanced organic materials.
• Academic & Industrial R&D: A vital reagent for methodological development and exploratory synthesis in organic chemistry laboratories.
• Nucleophilic Alkylation Reactions: Primarily used to add the (1-ethylbutyl) group to various electrophiles such as carbonyl compounds (aldehydes, ketones, esters) and epoxides.

Quality Control

Our (1-Ethylbutyl)Magnesium Bromide is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Quality is assured through analytical techniques including titration (for assay/concentration) and gas chromatography (GC). A comprehensive Certificate of Analysis (COA) detailing purity, concentration, and solvent content is provided with each shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this reagent must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for extended stability. Keep away from heat, sparks, open flames, and incompatible materials such as moisture, acids, and oxidizing agents.
