For procurement managers and R&D scientists in the chemical and pharmaceutical industries, understanding chemical specifications is fundamental to making informed purchasing decisions. These specifications are the language that defines a chemical's identity, quality, and suitability for a particular application. Let's break down the key elements using 2-Propyl-1H-imidazole-4,5-dicarboxylic acid (CAS: 58954-23-7) as an example.

Chemical Name and Synonyms: The chemical name, 2-Propyl-1H-imidazole-4,5-dicarboxylic acid, precisely describes its molecular structure. Synonyms, if provided, can help in cross-referencing and searching, although it's the CAS number that offers unambiguous identification. For this compound, the CAS number 58954-23-7 is critical for ensuring you are sourcing the correct substance, preventing costly mix-ups.

Molecular Formula and Molecular Weight: These parameters, C8H10N2O4 and 198.17600 respectively, provide fundamental information about the elemental composition and mass of a single molecule. They are essential for stoichiometric calculations in synthesis and for understanding the basic chemical identity.

Physical and Chemical Properties: This section details characteristics like density (1.464 g/cm3), boiling point (552.885ºC at 760 mmHg), and appearance. For 2-Propyl-1H-imidazole-4,5-dicarboxylic acid, its appearance is noted as a 'White powder'. This visual cue is important for initial identification and quality checks upon receipt. Properties like melting point and flash point, if available, are also crucial for safe handling and storage.

Specifications: This is arguably the most critical section for buyers. It outlines the acceptable quality parameters. For 2-Propyl-1H-imidazole-4,5-dicarboxylic acid, key specifications include:

  • Appearance: White powder (as mentioned).
  • Purity: ≥98%. This indicates the minimum percentage of the desired compound in the product. Higher purity often means higher cost but is essential for sensitive applications like API synthesis.
  • Moisture Content: ≤0.2%. Water can interfere with chemical reactions or degrade the compound. Low moisture is therefore highly desirable.
  • Impurity: ≤0.3%. This defines the maximum allowable level of unwanted substances.
