Description

1,11-Dibromoundecane is a high-purity, long-chain aliphatic dibromide compound, serving as a versatile and critical building block in advanced organic synthesis. Its value lies in its bifunctional reactivity, where the two terminal bromine atoms act as excellent leaving groups for nucleophilic substitution and coupling reactions, enabling the precise construction of complex molecular architectures. This makes it an essential intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries, particularly for synthesizing macrocycles, liquid crystals, and functionalized surfactants.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), especially in creating long-chain linkers and macrocyclic compounds.
• Agrochemical Synthesis: Used in the production of specialized pesticides, herbicides, and plant growth regulators requiring specific alkane chain lengths.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for producing specialty polymers, polyesters, and liquid crystalline materials.
• Organic Synthesis Reagent: A fundamental reagent in nucleophilic substitution reactions (e.g., Williamson ether synthesis) and in the preparation of Grignard reagents.
• Surfactant & Detergent Precursor: Used to synthesize bifunctional surfactants and quaternary ammonium compounds with specific chain properties.
• Research & Development: Essential for academic and industrial R&D in organic chemistry for constructing complex organic molecules and studying reaction mechanisms.

Quality Control

Our 1,11-Dibromoundecane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including GC, HPLC, and NMR, to verify identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, bases, and oxidizing agents. Due to its nature as a strong acid/organic solvent, ensure containers are kept tightly sealed to prevent moisture absorption and potential decomposition.
