For chemists, formulators, and procurement specialists, a thorough understanding of product specifications is fundamental to ensuring the suitability and performance of chemical intermediates. 2,3-Dimethylbenzaldehyde (CAS 5779-93-1) is no exception. This guide breaks down the key specifications for this aromatic aldehyde, helping you make informed purchasing decisions and ensuring the quality of your raw materials.

Decoding the Specifications of 2,3-Dimethylbenzaldehyde

When you look to buy 2,3-Dimethylbenzaldehyde, pay close attention to the following critical parameters, which are typically detailed in supplier product sheets and Certificates of Analysis (CoAs):

  • Chemical Name and Synonyms: While universally identified by its IUPAC name, 2,3-Dimethylbenzaldehyde, it is also known by synonyms such as O-Xylene-3-carboxaldehyde, Hemellitaldehyde, or Dimethylbenzaldehyde. Familiarity with these synonyms aids in comprehensive searching.
  • CAS Number: The Chemical Abstracts Service (CAS) registry number, 5779-93-1, is the definitive identifier for this chemical compound, ensuring you receive the exact substance required.
  • Molecular Formula: C9H10O accurately represents the elemental composition of the molecule.
  • Molecular Weight: At approximately 134.18 g/mol, this value is crucial for stoichiometric calculations in synthesis.
  • Purity: This is arguably the most critical specification for any chemical intermediate. For 2,3-Dimethylbenzaldehyde, a common purity level offered by manufacturers is 97%. Higher purities may be available upon request for specialized applications. Purity is typically determined by analytical techniques such as Gas Chromatography (GC).
  • Appearance: Suppliers generally describe 2,3-Dimethylbenzaldehyde as a liquid that ranges in color from colorless to pale yellow. Significant deviation from this description could indicate impurities or degradation.
  • Boiling Point: The boiling point provides an indication of volatility and is often reported under reduced pressure. For 2,3-Dimethylbenzaldehyde, it's commonly cited as 86-88 °C at 10 mmHg.
  • Density: The density, typically around 1.029 g/mL at 25 °C, is useful for volume-to-mass conversions and quality checks.
  • Refractive Index: A refractive index (n20/D) of approximately 1.553 is another physical constant used for identification and quality control.
  • Flash Point: The flash point, often around 101 °C (214 °F), indicates the lowest temperature at which the vapor can ignite in the presence of an ignition source, relevant for safety and handling.
  • Storage Conditions: Proper storage, often recommended at -20°C under an inert atmosphere, is vital to maintain the compound's stability and purity over time.
