For industries relying on precise chemical inputs, understanding the detailed specifications of raw materials like 1-Bromo-3-ethynylbenzene (CAS 766-81-4) is crucial for successful application and consistent results. This compound serves critical functions as both a sensitive acid-base indicator and a valuable intermediate in various synthesis pathways. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier, emphasizes the importance of clear specifications for our clients in the pharmaceutical, agrochemical, and specialty chemical sectors.

The most critical specification for 1-Bromo-3-ethynylbenzene is its purity, often quoted at 98% or higher. This level of purity is essential for its role as an acid-base indicator, ensuring a sharp and predictable color change within its designated pH range (2.9-4.0, red to yellow). For synthetic applications, high purity minimizes side reactions and ensures the integrity of the final product, whether it's an Active Pharmaceutical Ingredient (API) or a novel material. When procuring, always request a Certificate of Analysis (CoA) that details the purity, along with other relevant parameters such as moisture content, and results from analytical techniques like NMR or HPLC.

The physical appearance of 1-Bromo-3-ethynylbenzene is consistently described as a white powder. This physical characteristic aids in its handling, weighing, and dissolution during laboratory and production processes. However, factors like particle size distribution can sometimes be important for specific formulation requirements. Understanding these physical attributes can help procurement managers and formulators make informed decisions. We ensure our product meets the expected appearance standards for reliable industrial use.

Furthermore, information regarding molecular weight (181.03 g/mol) and molecular formula (C8H5Br) is fundamental for stoichiometric calculations in synthesis. Boiling point (around 198.24°C) and density (1.4466) are also key physical properties that inform process design and safety protocols. Proper storage, typically in a cool, dry place, away from light and under an inert atmosphere like nitrogen or argon, is vital to maintain the compound's quality over time. As a supplier, we provide this essential data to facilitate your operations.
