1-Bromo-3-ethylbenzene (CAS: 2725-82-8) is a fundamental organic chemical intermediate whose synthesis and properties are of great interest to chemists in various industries. Understanding its production pathways and inherent characteristics is key to its effective utilization. This compound, an aromatic halide, is typically synthesized through well-established chemical processes, ensuring its availability for commercial applications.

One common method for producing 1-Bromo-3-ethylbenzene involves the diazotization of 3-ethylaniline followed by a Sandmeyer-type reaction using copper(I) bromide and hydrobromic acid. This process allows for the regioselective introduction of the bromine atom at the desired meta position relative to the ethyl group. The successful execution of this synthesis route requires careful control of reaction conditions, including temperature and reagent addition rates, to maximize yield and purity. Researchers looking to buy this compound can often find detailed synthesis information from leading suppliers.

Chemically, 1-Bromo-3-ethylbenzene is characterized as a clear, colorless to light yellow liquid. Its physical properties, such as a melting point around -20.49°C (estimated) and a boiling point of 85°C (at 10mm Hg), indicate it is handled as a liquid under typical laboratory and industrial conditions. Its density is approximately 1.3493 g/cm³, and its refractive index is around 1.5465. These properties are important for storage, handling, and process design.

The compound's stability is generally good under normal temperatures and pressures, though it is recommended to store it in a dry, cool, and sealed environment, protected from exposure to air. For businesses that require a steady supply, identifying reliable manufacturers who can consistently produce high-quality 1-Bromo-3-ethylbenzene at competitive prices is crucial for smooth operations and product development.
