For B2B professionals in the chemical industry, a deep understanding of a compound's technical specifications is fundamental to its successful application. 1-Phenyl-2-nitroethanol (CAS 15990-45-1) is no exception. This chemical, often used as a pharmaceutical intermediate and in diagnostic reagents, possesses a distinct set of properties that dictate its utility. This article provides a technical overview, empowering you to make informed sourcing decisions and optimize your research and development efforts.

Chemical Identity and Structure

Product Name: 1-Phenyl-2-nitroethanol
CAS Number: 15990-45-1
Molecular Formula: C8H9NO3
Molecular Weight: 167.16 g/mol
Synonyms: Benzenemethanol, α-(nitromethyl)-; Benzyl alcohol, α-(nitromethyl)-; 1-Phenyl-2-nitroethanol; 2-Nitro-1-phenylethanol; NSC 17692; NSC 23616.

The molecular structure features a phenyl ring attached to a carbon atom bearing a hydroxyl group (-OH) and a nitro-substituted ethyl chain (-CH2NO2). This combination of functional groups—an alcohol and a nitroalkane—confers specific reactivity, making it a valuable intermediate in organic synthesis.

Key Physical and Chemical Properties

Understanding the physical and chemical properties is crucial for handling, storage, and application design. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. typically provide detailed specifications:

  • Appearance: White powder. This form is generally easy to handle and weigh accurately in laboratory and industrial settings.
  • Purity: Commonly offered at 98% or higher. High purity is critical for pharmaceutical and diagnostic applications to ensure reaction specificity and product reliability. When you buy, always verify the Certificate of Analysis (CoA).
  • Density: Approximately 1.254 g/cm³. This value is useful for volume-to-mass conversions in formulations and process design.
  • Boiling Point: 317.2 °C at 760 mmHg. This high boiling point suggests relatively low volatility at room temperature.
  • Flash Point: 142.5 °C. This indicates a moderate flammability hazard, requiring appropriate handling precautions.

Applications and Reactivity Considerations

As a pharmaceutical intermediate, 1-Phenyl-2-nitroethanol’s hydroxyl group can be esterified or etherified, while the nitro group can be reduced to an amine, a common step in the synthesis of many drugs. Its presence in diagnostic reagents often relates to its role as a precursor or a structural element within a larger functional molecule.
