For B2B buyers in the chemical and materials industries, a thorough understanding of a product's chemical properties is paramount before making a purchase decision. 1,6-Dibromo-3,8-diisopropylpyrene (CAS: 869340-02-3) is a specialized intermediate with distinct characteristics that make it valuable for advanced applications, particularly in OLEDs and complex organic synthesis. As a leading manufacturer and supplier, we aim to provide clarity on these properties to facilitate informed purchasing.

The molecular formula of this compound is C22H20Br2, with a molecular weight of approximately 444.20 g/mol. This gives us a precise understanding of its composition. Key physical and chemical properties reported for 1,6-dibromo-3,8-diisopropylpyrene include a predicted boiling point of 512.4±45.0 °C at 760 mmHg and a density of around 1.5±0.1 g/cm³. Its appearance is typically described as a white crystalline powder, a common form for many organic intermediates, which is convenient for handling and storage. The high molecular weight and the presence of bromine atoms contribute to its specific reactivity and physical behavior.

The most significant aspect for synthesis applications is the presence of two bromine atoms at the 1 and 6 positions and two isopropyl groups at the 3 and 8 positions on the pyrene core. The isopropyl groups can influence solubility and steric effects, potentially impacting reaction selectivity. The bromine substituents are excellent leaving groups, making them ideal for undergoing various palladium-catalyzed cross-coupling reactions. These reactions are crucial for building larger, more complex organic molecules, which is why this compound is a sought-after intermediate in both OLED material development and pharmaceutical synthesis.

Procurement managers and R&D scientists must consider these properties when evaluating suppliers. A reputable manufacturer will not only provide accurate property data but also ensure consistent purity. For 1,6-dibromo-3,8-diisopropylpyrene, a purity of 97% minimum is standard for most high-value applications. This level of purity minimizes interference from byproducts in sensitive reactions, thereby ensuring predictable outcomes and high-quality final products. When you buy this chemical, partnering with a Chinese supplier like us means accessing cost-effective solutions without compromising on quality.

Understanding the storage conditions is also vital. Typically, such compounds should be preserved in well-closed, light-resistant, and airtight containers, stored at room temperature, and kept in a dark place to maintain their integrity over time. By providing comprehensive details on chemical properties, applications, and handling, we aim to support our B2B customers in making informed decisions. If you are looking to purchase 1,6-dibromo-3,8-diisopropylpyrene, understanding its properties is the first step towards a successful collaboration with a reliable chemical manufacturer.
