In the complex world of chemical procurement, having access to detailed product specifications and a clear understanding of applications is crucial for making informed purchasing decisions. 1,3-Dibromo-5-fluorobenzene (CAS 1435-51-4) is a high-value intermediate with diverse applications, and prospective buyers need precise information to ensure it meets their project requirements. This guide outlines the key specifications and uses of this versatile compound, highlighting why sourcing from a reliable manufacturer and supplier is essential.

Product Specifications: What Buyers Need to Know

When considering the purchase of 1,3-Dibromo-5-fluorobenzene, several technical specifications are critical:

• Chemical Name: 1,3-Dibromo-5-fluorobenzene
• CAS Number: 1435-51-4
• Molecular Formula: C6H3Br2F
• Molecular Weight: Approximately 253.89 g/mol
• Appearance: Typically described as a light yellow liquid. The exact color may vary slightly between batches, but this is a standard characteristic.
• Purity: This is a critical parameter. Buyers should look for suppliers offering a minimum purity of ≥95% or, for more demanding applications like pharmaceutical synthesis, ≥98%. Purity is usually determined by Gas Chromatography (GC).
• Boiling Point: Around 204-206 °C at 768 mmHg. This indicates its volatility and behavior under different temperature conditions.
• Density: Approximately 2.018 g/mL at 25 °C. This physical property is useful for handling and volumetric calculations.
• Refractive Index: Typically around n20/D 1.577. This optical property can be a quick check for material identity and purity.
• Flash Point: Generally greater than 110 °C. This indicates its relative flammability and is important for safety handling.
• Stability: Stable under normal temperature and pressure. However, like many organic chemicals, it should be stored appropriately (e.g., in a cool, dry place, away from incompatible materials).
• Packaging: Available in various sizes, from research quantities (e.g., 5g, 25g, 100g) to bulk industrial drums (e.g., 25kg).

Key Applications Driving Demand
