For any chemical synthesis endeavor, the quality of raw materials is paramount. When procuring Methyl 2-Hydroxy-4-Nitrobenzoate (CAS 13684-28-1), whether for pharmaceutical research, agrochemical development, or fine chemical manufacturing, understanding key quality indicators is essential. A trusted supplier provides not just the chemical but also the assurance of its performance in your specific application.

The most critical quality parameter for Methyl 2-Hydroxy-4-Nitrobenzoate is its purity. Typically, this is expressed as a percentage, often determined by techniques such as HPLC (High-Performance Liquid Chromatography) or GC (Gas Chromatography). A higher purity level, commonly above 95% or even 98%, is usually preferred for sensitive applications like pharmaceutical intermediate synthesis. When you purchase from a reputable manufacturer, expect a detailed Certificate of Analysis (CoA) that clearly states the assay and the levels of any identified impurities.

Another important aspect is the physical form and appearance. Methyl 2-Hydroxy-4-Nitrobenzoate is generally described as a light yellow to brown solid. Any significant deviation from this description, or the presence of foreign matter, could indicate contamination or degradation. Suppliers should provide clear specifications on appearance to allow for easy visual verification upon receipt.

Furthermore, reliable suppliers will offer comprehensive documentation. This includes the CAS number (13684-28-1) for unambiguous identification, the molecular formula (C8H7NO5), and molecular weight (197.14). Safety Data Sheets (SDS) are also crucial, detailing handling precautions, hazard statements, and emergency procedures. When looking to buy this intermediate, always inquire about the availability and completeness of these documents from your potential manufacturer.

Ultimately, selecting a chemical supplier for Methyl 2-Hydroxy-4-Nitrobenzoate should involve a thorough assessment of their quality management systems, technical capabilities, and customer support. Partnering with a manufacturer that prioritizes these aspects ensures that your procurement efforts yield high-quality materials, vital for the success of your research and production goals.
