Physical and Chemical Characteristics

The physical and chemical properties of 3,5-Difluorophenylacetonitrile dictate its handling, storage, and application:

• Appearance: It is typically described as a White to yellowish solid, though some sources may list it as a powder to lump or even a clear liquid depending on purity and temperature. For procurement purposes, confirming appearance with the manufacturer is advisable.
• Melting Point: A key indicator of purity, its melting point ranges from 35-38 °C. This relatively low melting point means it can be a solid at room temperature but may melt easily.
• Boiling Point: The boiling point is approximately 204.4 ± 25.0 °C, indicating its relative volatility under standard pressure.
• Density: Typically around 1.234 ± 0.06 g/cm³, this value is useful for volumetric calculations.
• Flash Point: Reported as >230 °F (>110 °C), classifying it as a combustible liquid with a relatively high flash point, suggesting moderate fire risk under normal conditions.
• Assay/Purity: Manufacturers commonly offer this compound with an assay of ≥99.0% or ≥98% (GC/HPLC), which is critical for its use as an intermediate where high purity is essential for reaction efficiency and product quality.

Storage and Handling Recommendations

Proper storage is vital to maintain the integrity of 3,5-Difluorophenylacetonitrile. Recommended conditions include:

• Keeping containers tightly sealed.
• Storing in a ventilated, low-temperature, dry warehouse.
• Separating from incompatible materials, such as strong oxidizing agents, and foodstuffs.

When you buy from a trusted supplier, these storage recommendations are typically provided along with safety data sheets (SDS) and Certificates of Analysis (CoA), ensuring you have all the necessary information for safe and effective use.

Understanding these technical specifications empowers R&D scientists and procurement specialists to make informed decisions when sourcing 3,5-Difluorophenylacetonitrile for their specific projects.
