For professionals working with chemicals, a thorough understanding of both the properties and safety aspects of a compound is essential. 1,12-Dibromododecane (CAS 3344-70-5) is a valuable organic intermediate with specific characteristics that dictate its handling, storage, and application. This article explores the key properties, stability, and safety considerations associated with this dibromoalkane, providing guidance for those looking to procure it from trusted manufacturers and suppliers.

Physically, 1,12-Dibromododecane typically presents as an off-white to pale brown crystalline solid. Its melting point generally falls within the range of 38-42 °C, meaning it can exist as a solid or a liquid depending on ambient temperature. This physical state is important for handling and dispensing. Chemically, the compound is characterized by its long, twelve-carbon aliphatic chain and the presence of two bromine atoms at the terminal positions. This structure confers moderate solubility in organic solvents like hot methanol, while it is largely insoluble in water. Its boiling point is notably high, often cited around 215 °C at 15 mmHg, which is relevant for purification via distillation.

Stability is a key consideration for any chemical intermediate. 1,12-Dibromododecane is generally considered stable under recommended storage conditions, which typically involve keeping it sealed in a dry environment at room temperature, away from direct sunlight and incompatible materials. It is combustible, and care should be taken to avoid ignition sources. The compound is incompatible with strong oxidizing agents, which could lead to hazardous reactions. Manufacturers and suppliers will usually provide specific storage recommendations to maintain product integrity and safety.

Safety is a critical aspect when handling 1,12-Dibromododecane. While specific toxicity data may vary, similar halogenated hydrocarbons can be irritants. Hazard statements often indicate that it may be harmful if swallowed or inhaled and can cause skin and eye irritation. Standard laboratory safety protocols should always be followed, including wearing appropriate personal protective equipment (PPE) such as gloves, safety goggles, and lab coats. Working in a well-ventilated area or under a fume hood is crucial to minimize exposure to vapors. Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS) provided by the supplier are indispensable resources for detailed safety information.

For those in need of this chemical, sourcing from reputable suppliers is vital. When you buy 1,12-Dibromododecane, look for manufacturers who clearly specify purity levels (e.g., 97%, 98%) and provide comprehensive safety data. Chinese manufacturers and suppliers often offer competitive pricing for this intermediate, making it accessible for both research and industrial applications. Ensuring a clear understanding of the product's physical and chemical properties, along with strict adherence to safety guidelines, will enable its effective and safe utilization in your chemical processes. Engaging with suppliers who provide excellent customer support can further facilitate a smooth procurement experience.
