For any chemical professional, a thorough understanding of a compound's properties and safe handling procedures is non-negotiable. 3,5-Dichloro-4-fluoronitrobenzene (CAS 3107-19-5) is a compound with distinct characteristics that necessitate careful management. This article delves into its key physical and chemical properties, alongside essential safety guidelines, crucial information for anyone looking to purchase or utilize this chemical.

Key Physical and Chemical Properties

3,5-Dichloro-4-fluoronitrobenzene typically presents as a white powder. Its melting point is generally reported around 44°C, and its boiling point is approximately 259.3°C, though predictions may vary. The density is around 1.622 g/cm³. As a halogenated nitroaromatic compound, it possesses a reactive nature that makes it a valuable synthetic intermediate. While it has limited solubility in water, it is soluble in many organic solvents, which is a key consideration for reaction design. Its chemical stability is moderate; exposure to high temperatures or strong reducing agents can lead to decomposition, potentially releasing hazardous fumes such as nitrogen oxides and chlorinated compounds.

Safety First: Handling and Storage Recommendations

Adherence to safety protocols is vital when working with 3,5-Dichloro-4-fluoronitrobenzene. The Globally Harmonized System (GHS) classifies it with hazard statements indicating it can cause skin irritation, serious eye irritation, and may cause respiratory irritation (H315, H319, H335). Therefore, it is imperative to use appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to prevent inhalation. Proper storage involves keeping the compound in tightly sealed containers at room temperature, protected from moisture and direct light, to maintain its stability and prevent degradation.

Procurement Considerations for Quality and Safety

When purchasing 3,5-Dichloro-4-fluoronitrobenzene, it is crucial to buy from reputable manufacturers who provide comprehensive Safety Data Sheets (SDS) and adhere to stringent quality control standards. These documents offer detailed information on hazards, first-aid measures, fire-fighting measures, and accidental release measures, which are indispensable for safe handling and emergency preparedness. Familiarizing yourself with the SDS before use is a critical step for any procurement manager or researcher. Many suppliers in China offer this product with high purity, ensuring reliability for research and industrial applications. Always ensure you receive accurate documentation with your purchase.

Understanding the properties and safety requirements of 3,5-Dichloro-4-fluoronitrobenzene allows for its effective and responsible use in various synthetic processes. Prioritizing safety and sourcing from trusted manufacturers ensures both operational integrity and successful research outcomes.
