For research and development scientists, precise technical specifications are the bedrock of successful experimentation. 2,5-Difluoromandelic Acid (CAS 207853-61-0), a valuable pharmaceutical intermediate, requires detailed information to ensure its appropriate application in synthetic chemistry and drug discovery. Understanding these specifications helps researchers confidently buy the right material.

Key Identification and Purity

The primary identifiers for this compound are its chemical name, 2,5-Difluoromandelic Acid, and its CAS number: 207853-61-0. These unique identifiers ensure that researchers are procuring the exact chemical entity they intend to use. The purity level is arguably the most critical specification. Typically, for pharmaceutical applications, a minimum purity of 99% is sought after. This high purity ensures minimal interference from impurities, leading to more predictable reaction outcomes and higher yields in complex synthetic steps. Researchers looking to buy should always confirm this specification with their supplier.

Molecular Structure and Properties

The molecular formula of 2,5-Difluoromandelic Acid is C8H6F2O3. Its molecular weight is approximately 188.13 g/mol. This information is crucial for stoichiometric calculations in synthesis. The structure features a benzene ring substituted with two fluorine atoms at the 2 and 5 positions, and an alpha-hydroxy acetic acid group. This specific arrangement dictates its reactivity and utility as a building block.

Physical Characteristics

The appearance of 2,5-Difluoromandelic Acid is typically described as an off-white powder. This physical state is convenient for handling, weighing, and dissolving in various solvents commonly used in organic synthesis. Other key physical properties that R&D scientists may consider include:

  • Density: Approximately 1.523 g/cm³. This value is useful for volume-to-mass conversions.
  • Melting Point: While not explicitly stated in all sources, mandelic acid derivatives often have distinct melting points that can serve as an indicator of purity.
  • Boiling Point: The boiling point is listed as 310.083 °C at 760 mmHg. This high boiling point suggests that the compound is relatively stable at room temperature and under typical laboratory heating conditions, but distillation might require specialized equipment or vacuum.
  • Flash Point: The flash point of 141.334 °C indicates a moderate flammability risk, requiring standard precautions during handling.

Sourcing with Confidence

Researchers aiming to buy 2,5-Difluoromandelic Acid can leverage these specifications when communicating with potential manufacturers and suppliers. Accurate technical data, coupled with reliable supplier information such as origin country (e.g., China), enables informed purchasing decisions and supports the successful execution of advanced chemical research projects.
