For procurement managers and research scientists, a thorough understanding of a chemical intermediate's technical specifications is crucial before making a purchase. 1-Bromooctadecane (CAS 112-89-0) is a prime example of such a compound, where detailed specifications guide its effective use in various organic synthesis applications. When you aim to buy 1-Bromooctadecane, scrutinizing these parameters ensures you receive a product that meets your exact needs.

The physical appearance of 1-Bromooctadecane is typically described as a white to pale yellow crystalline solid. Its melting point generally falls within the range of 28-32°C, indicating it can exist as a solid or a low-melting solid at ambient temperatures. This characteristic is important for handling and storage considerations.

Key chemical properties include its molecular formula, C18H37Br, and a molecular weight of approximately 333.39 g/mol. Its solubility profile is also vital: it is insoluble in water but readily dissolves in common organic solvents like ethanol, ether, and chloroform. This property dictates suitable reaction media and purification methods.

Purity is arguably the most critical specification. High-grade 1-Bromooctadecane is often specified with a purity of ≥99.0% as determined by Gas Chromatography (GC) analysis. For specialized applications, such as pharmaceutical synthesis, additional purity metrics like low moisture content (≤0.5% by Karl Fischer titration) and controlled heavy metal levels are also critical. Suppliers who provide detailed Certificates of Analysis (CoA) demonstrating adherence to these specifications are highly valued.

Other important technical data include its boiling point, which can vary with pressure (e.g., 210°C at 12 mmHg), and its refractive index, typically around 1.463. Understanding these parameters helps in process design and quality control during synthesis.

When sourcing 1-Bromooctadecane, especially from manufacturers in China, requesting comprehensive technical data sheets and CoAs is standard practice. This diligence ensures that the product purchased aligns with the stringent requirements of organic synthesis, enabling reliable outcomes for all industrial and research purposes. Choosing a supplier that prioritizes transparent and accurate specification reporting is a hallmark of a professional chemical provider.
