2-Hydrazinoethanol (CAS 109-84-2), also known by synonyms such as Hydroxyethyl Hydrazine or HEH, is a bifunctional organic compound with significant utility in various industrial sectors. Understanding its chemical properties, common applications, and necessary safety protocols is crucial for anyone involved in its procurement, handling, or use. For those looking to buy 2-hydrazinoethanol, this overview provides essential insights.

Chemical and Physical Properties:

2-Hydrazinoethanol is typically described as a colorless to pale yellow viscous liquid. It possesses a characteristic amine-like odor. Key physicochemical properties include a density of approximately 1.12 g/cm³ at 20°C, a melting point around -30°C, and a boiling point of around 220°C (with decomposition). It is miscible with water, ethanol, and other polar organic solvents, which facilitates its use in various reaction media. With a purity often exceeding 98.5%, it is suitable for demanding applications, especially as a pharmaceutical intermediate.

Industrial Applications:

The versatility of 2-Hydrazinoethanol stems from its reactive hydrazine and hydroxyl functional groups:

  • Pharmaceutical Intermediates: HEH is a vital precursor in the synthesis of numerous pharmaceuticals, including antibiotics and antitumor agents. Its precise role in these syntheses makes it a high-value intermediate for drug manufacturers.
  • Polymer Modification: It serves as an effective crosslinking agent for materials like epoxy resins, improving their mechanical strength, thermal stability, and chemical resistance. This is crucial for coatings, adhesives, and composites.
  • Metal Treatment: HEH acts as a corrosion inhibitor in industrial cooling systems and other metal treatment processes, protecting metal surfaces from degradation.
  • Specialty Chemicals: It is a key building block in the synthesis of various heterocyclic compounds used in agrochemicals, dyes, and other specialized chemical formulations.

Safety and Handling:

Given its chemical nature, 2-Hydrazinoethanol requires careful handling. It is classified as toxic if swallowed and can cause skin irritation, serious eye irritation, and respiratory irritation. Safety precautions include wearing appropriate personal protective equipment (PPE) such as gloves, safety goggles, and protective clothing. Ensure adequate ventilation in work areas to avoid inhalation of vapors. Storage should be in cool, dry conditions, sealed under an inert atmosphere, and potentially in a freezer below -20°C, as indicated by some suppliers, to maintain stability. Always consult the Material Safety Data Sheet (MSDS) provided by the manufacturer for detailed safety information.

Procuring 2-Hydrazinoethanol from a reputable manufacturer ensures adherence to quality specifications and provides access to vital safety data. Understanding these aspects is fundamental for safe and effective utilization in your industrial processes.
