1,8-Dibromonaphthalene(CAS: 17135-74-9)

1,8-Dibromonaphthalene (CAS: 17135-74-9) is a crystalline solid with a molecular weight of approximately 270.07 g/mol. It has a high melting point of 222–224 °C and is slightly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is less reactive than naphthalene but can undergo electrophilic substitution reactions. It is commonly used as a starting material in organic synthesis and as a halogenated aromatic compound in various applications.

1,8-Dibromonaphthalene (CAS: 17135-74-9) can be synthesized by brominating naphthalene in the presence of a Lewis acid catalyst such as aluminum bromide. The reaction involves the selective bromination of the naphthalene ring, followed by workup and purification. The yield is typically around 80-85%, and the method is commonly used in academic and industrial settings for the production of brominated derivatives.

1,8-Dibromonaphthalene (CAS: 17135-74-9) is used in various industries, including pharmaceuticals, where it serves as a precursor for the synthesis of drugs, and in polymers, where it can be used as a comonomer. It is also utilized in the production of sensors and semiconductors due to its unique chemical properties and reactive nature.

When handling 1,8-Dibromonaphthalene (CAS: 17135-74-9), appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. The compound should be stored in a sealed container in a cool, dry place away from sources of ignition. Fume hoods should be used during handling to minimize exposure. In case of spill, the area should be cleaned up immediately using appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for specific instructions. Proper disposal methods should also be followed, and it is advisable to work in a well-ventilated area to ensure safety.
