1-Bromonaphthalene, identified by its CAS number 90-11-9, is a compound that plays a significant role in various scientific and industrial applications. Its unique physical and chemical characteristics make it a valuable resource for researchers and manufacturers alike. This article, brought to you by NINGBO INNO PHARMCHEM CO.,LTD., aims to provide a comprehensive understanding of 1-Bromonaphthalene, from its basic properties to its diverse applications and considerations for purchase.

Physically, 1-Bromonaphthalene is typically a colorless liquid with a distinct aromatic odor. It has a molecular weight of approximately 207.07 g/mol and a density of around 1.48 g/mL. Its melting point is slightly below room temperature, around -2 to -1 °C, while its boiling point is significantly higher, typically in the range of 279-281 °C at atmospheric pressure. This liquid form, combined with its specific solubility profile—miscible with common organic solvents like ethanol, ether, and benzene, but only slightly soluble in water—makes it suitable for a range of chemical processes. When looking to buy 1-bromonaphthalene, these properties are crucial for determining its suitability for a particular application.

Chemically, 1-Bromonaphthalene is an aryl bromide, meaning the bromine atom is directly attached to the naphthalene aromatic system. This structural feature renders it reactive in nucleophilic substitution reactions and various transition-metal-catalyzed cross-coupling reactions. Its utility as a solvent is also noteworthy. It can serve as a medium for reactions requiring a non-polar environment, aiding in the dissolution of hydrophobic compounds. Furthermore, its high refractive index (around 1.657) makes it useful in refractometry, where it can be employed to determine the refractive index of crystals or to measure the water content in alcohols, contributing to precise analytical chemistry.

The applications of 1-Bromonaphthalene are broad and impactful. It is a key precursor in the synthesis of dyes and pigments, contributing to the vibrant colors seen in textiles and coatings. In the realm of material science, it is used in the development of advanced materials, including organic semiconductors and optoelectronic devices, due to the electronic properties imparted by the naphthalene structure. Researchers focusing on environmental chemistry may also utilize 1-Bromonaphthalene to study the behavior of polycyclic aromatic hydrocarbons (PAHs) in the environment. The price of 1-bromonaphthalene can vary based on purity and quantity, but its utility often makes it a worthwhile investment for these specialized fields.

For those in need of this versatile chemical, sourcing high-quality 1-Bromonaphthalene from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD. is essential. Ensuring the purity and consistency of the product is vital, particularly for sensitive applications in pharmaceuticals and advanced materials. Whether you are looking to purchase 1-bromonaphthalene for synthesis, analysis, or material development, understanding its properties and applications will guide your selection process and ensure successful project outcomes.
