Description

Undecylbromomagnesium is a highly reactive organomagnesium compound, specifically a Grignard reagent, with the CAS number 117286-10-9. This chemical is a critical building block in synthetic organic chemistry, enabling the efficient introduction of an undecyl (C11) chain into target molecules. It is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise carbon chain elongation and functional group transformations.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for constructing long-chain alkyl segments in active pharmaceutical ingredients (APIs) and drug candidates.
• Agrochemical Production: Used in the synthesis of surfactants, adjuvants, and active compounds requiring specific lipophilic (fat-soluble) properties.
• Specialty Polymer & Material Science: Serves as a monomer or modifier in the creation of polymers with tailored surface properties and chain lengths.
• Liquid Crystal & OLED Material Development: Employed to synthesize organic molecules with precise alkyl chain lengths for electronic display applications.
• Flavor & Fragrance Chemistry: Facilitates the synthesis of macrocyclic musks and other fragrance compounds with undecyl backbones.
• Organic Synthesis Research: A versatile tool in academic and industrial R&D for nucleophilic addition reactions to carbonyl groups (ketones, aldehydes, esters).

Quality Control

Our Undecylbromomagnesium is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for your critical syntheses. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as concentration (typically supplied as a solution in THF or diethyl ether), assay, and impurity profiles. Our quality system is designed to meet the exacting standards of GMP and ISO-guided manufacturing environments.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive and moisture-sensitive nature, this product must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures of 2°C to 8°C. The container should be kept in a cool, dry, well-ventilated area away from incompatible materials such as acids, oxidizers, and moisture sources. Always handle and store under strict exclusion of air and water to maintain potency and safety.
