For procurement managers and R&D scientists in the pharmaceutical and fine chemical industries, understanding the precise specifications of a chemical intermediate is vital. 2,4-Difluoro-3,5-dimethoxybenzoic acid (CAS: 1003709-80-5) is a prime example of a compound where quality directly impacts the success of synthesis and the integrity of the final product. This article delves into the crucial specifications and quality parameters you should look for when sourcing this important intermediate from manufacturers.

Key Specifications for 2,4-Difluoro-3,5-dimethoxybenzoic Acid

When you decide to buy 2,4-Difluoro-3,5-dimethoxybenzoic acid, paying close attention to its specifications is non-negotiable. Manufacturers typically provide the following critical data:

  • CAS Number: 1003709-80-5. This unique identifier ensures you are sourcing the correct compound.
  • Molecular Formula: C9H8F2O4. This defines the atomic composition of the molecule.
  • Molecular Weight: 218.15 g/mol. Essential for stoichiometric calculations in synthesis.
  • Appearance: Typically described as a white powder. Any deviation from this could indicate impurities or improper storage.
  • Purity (Assay): This is arguably the most important specification. For 2,4-Difluoro-3,5-dimethoxybenzoic acid, a minimum purity of 98.0% is commonly stated by reputable manufacturers. Higher purity levels (e.g., 99%+) may be available for highly specialized applications, but often come at a premium. Always check if the assay method (e.g., HPLC, GC) is specified.
  • Related Impurities: While not always explicitly listed in summary datasheets, a thorough Certificate of Analysis (CoA) from a reliable manufacturer will detail specific known impurities and their maximum allowable limits. This is crucial for controlling side reactions and ensuring the final API's purity.
  • Moisture Content: For many organic solids, moisture can affect stability and reactivity. Manufacturers often specify a maximum moisture content.
  • Solubility: While often insoluble in water, understanding its solubility in common organic solvents is important for reaction setup.
