Description

11-Bromoundecanoyl Chloride is a versatile bifunctional organic intermediate featuring both a reactive acid chloride group and a terminal bromoalkyl chain. This compound is essential for the synthesis of complex molecules, enabling the precise introduction of an 11-carbon spacer arm with a terminal functional handle. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for applications such as polymer modification, bioconjugation, and the development of liquid crystals and surfactants.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring long-chain hydrophobic linkers.
• Bioconjugation Reagent: Used to attach peptides, proteins, or other biomolecules to surfaces, polymers, or fluorescent probes via its reactive acid chloride group.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for producing specialty polyesters, polyamides, and functionalized polymers with specific chain lengths.
• Liquid Crystal Synthesis: A crucial precursor for creating mesogenic compounds with defined alkyl chain lengths for display and optical applications.
• Surfactant & Lipid Chemistry: Employed in the synthesis of novel cationic lipids for gene delivery (lipofection) and non-ionic surfactants.
• Agrochemical Intermediates: Used in the production of herbicides, fungicides, and plant growth regulators that incorporate long-chain bromoalkyl motifs.
• Organic Synthesis: A valuable reagent for nucleophilic substitution reactions (via the bromine) and acylations (via the acid chloride), facilitating multi-step synthetic routes.

Quality Control

Our 11-Bromoundecanoyl Chloride is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your R&D and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C (refrigerated) or as specified on the label. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
