2,2-Difluoroacetamide: Bulk Supply & Technical Specs
Technical Specifications and Purity Grades of 2,2-Difluoroacetamide (CAS 359-38-6)
2,2-Difluoroacetamide, also known as acetamide 2,2-difluoro or difluoroacetamide, is a fluorinated amide with the molecular formula C2H3F2NO. This compound serves as a critical pharma intermediate and agrochemical building block, valued for its ability to introduce fluorine atoms into target molecules. As a fluorine reagent, it enables the synthesis of active pharmaceutical ingredients (APIs) and crop protection agents with enhanced metabolic stability and bioavailability. NINGBO INNO PHARMCHEM CO.,LTD. supplies this product with a focus on industrial purity and batch-to-batch consistency, ensuring it meets the rigorous demands of organic synthesis and manufacturing processes.
Our standard offering includes a high-purity grade (≥98% by GC) suitable for most synthetic applications. For specialized requirements, we can provide custom purities upon request. The table below summarizes the typical technical parameters for our 2,2-difluoroacetamide:
| Parameter | Specification | Test Method |
|---|---|---|
| Appearance | White to off-white crystalline powder | Visual |
| Purity (GC) | ≥98.0% | GC-FID |
| Melting Point | 52–56°C | DSC |
| Moisture (KF) | ≤0.5% | Karl Fischer |
| Residue on Ignition | ≤0.1% | Gravimetric |
These specifications are representative; please refer to the batch-specific COA for exact values. The compound's relatively low melting point necessitates careful handling during storage and transport, particularly in warmer climates.
Certificate of Analysis (COA) Parameters and Batch Consistency for Industrial Procurement
For procurement managers, the Certificate of Analysis (COA) is the definitive document that validates product quality. Our COA for 2,2-difluoroacetamide includes not only the standard parameters listed above but also additional tests critical for sensitive applications. For instance, trace impurity profiles—including residual solvents and heavy metals—are monitored to ensure compliance with pharmacopeial guidelines. We understand that in organic synthesis, even minor variations in impurity levels can impact reaction yields or downstream purification steps. Therefore, we maintain strict batch consistency through validated manufacturing processes and in-process controls.
One often-overlooked aspect is the control of the synthesis route. Our manufacturing process is optimized to minimize the formation of regioisomers or over-fluorinated byproducts, which can be challenging to separate. This attention to detail ensures that the difluoroacetamide you receive performs predictably in your chemistry. For advanced analytical applications, such as qNMR, we have published detailed studies on baseline drift and moisture management. You can explore our findings in the article Qnmr用2,2-ジフルオロアセトアミド：ベースラインドリフトと水分管理, which discusses how our product's purity profile minimizes interference in quantitative NMR. Similarly, our Russian-language resource 2,2-Дифторацетамид Для Qnmr: Контроль Дрейфа Базовой Линии И Влажности provides additional technical insights.
Bulk Packaging, Storage, and Handling: IBC Totes, 210L Drums, and Cold-Chain Logistics
We offer 2,2-difluoroacetamide in packaging configurations tailored to industrial-scale operations. Standard options include 210L steel drums with polyethylene liners and intermediate bulk containers (IBC totes) for larger volumes. Each container is purged with nitrogen to maintain product integrity during transit. While the product is stable under recommended conditions, its low melting point (52–56°C) means that in hot climates or during summer months, partial melting may occur. This does not affect chemical purity, but it can complicate material handling. To mitigate this, we advise storing the product in a cool, dry area below 25°C. For shipments to regions with extreme temperatures, we can arrange cold-chain logistics using refrigerated containers to ensure the material remains in its crystalline form.
Proper handling procedures are essential. Personnel should wear appropriate personal protective equipment (PPE) including gloves and safety goggles. Avoid inhalation of dust and ensure adequate ventilation. Detailed safety information is provided in the Safety Data Sheet (SDS), which accompanies every shipment.
Non-Standard Field Parameters: Viscosity Shifts, Crystallization Behavior, and Trace Impurity Profiles
Beyond the standard specifications, our field experience has revealed several non-standard parameters that can impact user operations. One notable behavior is the viscosity shift of molten 2,2-difluoroacetamide at sub-zero temperatures. While the product is typically handled as a solid, some processes involve melting it for liquid-phase reactions. We have observed that upon cooling below 0°C, the melt exhibits a significant increase in viscosity before solidification, which can affect pumpability in continuous flow systems. This is not a purity issue but a physical property inherent to the compound. Pre-heating transfer lines or using jacketed equipment can alleviate this.
Another practical consideration is crystallization behavior. If the product melts during storage and then re-solidifies, it may form a solid mass that is difficult to discharge from drums. To restore free-flowing powder, we recommend gently warming the container to 40–50°C and then slowly cooling with agitation. This procedure promotes the formation of smaller, more manageable crystals. Additionally, trace impurities—particularly residual acetic acid or fluoride ions—can subtly influence the color of the final product. While our specification allows for an off-white appearance, we have found that controlling the synthesis route to keep these impurities below 0.1% ensures a consistently white powder, which is often preferred for aesthetic reasons in formulated products.
