For professionals in the chemical and pharmaceutical industries, a deep understanding of product specifications is crucial for making informed purchasing decisions. This is particularly true for key intermediates like 3-Fluoro-4-morpholinoaniline (CAS 93246-53-8), a compound vital for the synthesis of the antibiotic Linezolid. When sourcing this material, paying close attention to its defined characteristics ensures that it meets the stringent requirements of pharmaceutical manufacturing.

The primary specifications for 3-Fluoro-4-morpholinoaniline typically include its appearance, assay (purity), loss on drying, and residue on ignition. As an off-white to brown crystalline powder, its physical form is readily identifiable. The assay, often determined by High-Performance Liquid Chromatography (HPLC), is a critical indicator of purity, with a standard requirement of ≥98.0%. This high purity level is essential to minimize impurities in the final drug product and ensure the efficacy and safety of Linezolid.

Loss on drying (LOD) is another important specification, typically set at ≤1.0%. This measurement indicates the amount of volatile matter, primarily moisture, present in the compound. Minimizing LOD is important for accurate weighing and for preventing unwanted reactions or degradation during storage and processing. Similarly, the residue on ignition, usually specified at ≤0.5%, helps to quantify inorganic impurities that might remain after the compound has been ignited.

The melting point is also a key physical property, with a typical range of 120-124°C for high-quality 3-Fluoro-4-morpholinoaniline. Deviations from this range can sometimes indicate impurities or variations in the crystalline structure. For manufacturers and bulk purchasers, understanding these specifications is fundamental to qualifying a supplier and ensuring the consistent quality of their raw materials.

When you choose to buy 3-Fluoro-4-morpholinoaniline from a reputable manufacturer, you can expect these specifications to be clearly documented and consistently met. This diligence in understanding and verifying specifications ensures that your procurement of this Linezolid intermediate contributes positively to your production processes. Prioritizing suppliers in China who adhere to these standards will significantly benefit your operations.
