Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
For any B2B procurement decision, a thorough understanding of product specifications is paramount. This is especially true for chemical intermediates like 1-Bromobenzocyclobutene (CAS 21120-91-2), which are vital components in complex synthesis processes. Procurement managers and R&D scientists need precise data to ensure the compound meets their application requirements and to facilitate efficient communication with manufacturers and suppliers.
The identification number, CAS 21120-91-2, is the universal identifier for 1-Bromobenzocyclobutene, ensuring you are sourcing the correct chemical. Beyond this, several key specifications define its quality and suitability for use:
Purity: This is arguably the most critical specification. For 1-Bromobenzocyclobutene, high purity, typically stated as 99% or higher, is essential, especially when used as a pharmaceutical intermediate. Lower purity can lead to unwanted side reactions, reduced yields, and potentially contamination of the final product. Always confirm the purity level with your supplier.
Molecular Formula and Weight: The molecular formula is C8H7Br, and its corresponding molecular weight is approximately 181.03 g/mol. This information is fundamental for stoichiometric calculations in synthesis reactions.
Appearance: 1-Bromobenzocyclobutene is generally described as a colorless to pale yellow liquid. Deviations from this appearance could indicate degradation or impurities, so it’s a useful visual check.
Density: A typical density value is around 1.589 g/cm³ at 20°C (or similar values like 1.45 g/mL at 25°C from other sources). Density is important for handling, storage, and volumetric calculations.
Boiling Point: The boiling point is approximately 220.3 °C at 760 mmHg. This figure is relevant for distillation and purification processes, as well as for understanding its volatility.
Flash Point: A flash point of 75.2 °C (or 205 °F) indicates the temperature at which the vapor can ignite in the presence of an ignition source. This is crucial for safe handling and transportation procedures.
When you contact a manufacturer or supplier for a quote on 1-Bromobenzocyclobutene, always ask for detailed specifications and a Certificate of Analysis (CoA). This document will provide verified data on the batch you are purchasing, assuring you of its quality. Understanding these specifications will empower you to make informed purchasing decisions and ensure the success of your chemical processes.
