This article delves into its key characteristics, offers guidance on safe handling, and provides insights for procurement professionals looking to buy this intermediate from trusted suppliers.

Physical and Chemical Characteristics

3,5-Dinitro-2-methylbenzoic acid is an organic molecule with the chemical formula C8H6N2O6. It typically manifests as an off-white to pale yellow crystalline powder. Key physical properties that influence its application include its melting point, which is generally observed in the range of 205-209°C. While specific solubility data can vary, it is important for formulators to consult the Safety Data Sheet (SDS) provided by the manufacturer for detailed information pertinent to their process. The compound’s structure, featuring two nitro groups and a carboxylic acid function, dictates its reactivity and utility in chemical synthesis.

Safe Handling and Storage Guidelines

As with many chemical intermediates, proper handling and storage are critical to maintain the integrity of 3,5-Dinitro-2-methylbenzoic acid and ensure workplace safety. Manufacturers typically provide specific recommendations:

  • Storage Conditions: It is advisable to store the compound in a cool, dry, and well-ventilated area, away from direct sunlight and sources of ignition. Keeping containers tightly sealed prevents moisture absorption and contamination.
  • Personal Protective Equipment (PPE): When handling, it is recommended to wear appropriate PPE, including chemical-resistant gloves, safety goggles or a face shield, and protective clothing. A dust mask or respirator may be necessary if handling generates airborne particles.
  • Incompatibilities: Avoid contact with strong oxidizing agents, strong bases, and reducing agents, as these can lead to hazardous reactions. Always refer to the SDS for a comprehensive list of incompatible materials.
  • Spill Response: In the event of a spill, it should be contained and cleaned up promptly using appropriate absorbent materials. Disposal should be carried out in accordance with local environmental regulations.

By adhering to these guidelines, users can safely and effectively utilize this chemical intermediate.

Where to Buy and What to Expect from Suppliers

For businesses requiring 3,5-Dinitro-2-methylbenzoic acid, sourcing from reputable manufacturers or distributors is key. When you intend to buy this chemical:

  • Verify Purity and Specifications: Always seek products with a clearly stated assay (e.g., ≥99%) and ensure it meets the technical requirements for your intended application, whether it's for pharmaceutical intermediates or dye synthesis.
  • Request Documentation: Obtain a Certificate of Analysis (CoA) for each batch, which confirms the product’s quality and adherence to specifications. A comprehensive SDS is also essential for safe handling.
  • Consider Manufacturer Location: Many high-quality chemical intermediates are manufactured in China. Reputable China-based manufacturers can offer competitive pricing and a reliable supply chain, provided they maintain stringent quality control.
  • Inquire about Packaging: Standard packaging often involves 25kg drums or bags, but it's wise to confirm packaging suitability for your needs and transport requirements.

Establishing a relationship with a reliable supplier ensures you have consistent access to this important chemical intermediate, supporting your ongoing research and production needs.
