Tert-Butyl Bromoacetate (CAS 5292-43-3) is a chemical compound widely used in organic synthesis, particularly in the pharmaceutical and agrochemical sectors. While its utility as an intermediate and alkylating agent is undeniable, understanding its properties, potential hazards, and implementing safe handling practices are crucial for anyone working with this substance.

Key Properties of Tert-Butyl Bromoacetate

Tert-Butyl Bromoacetate is typically described as a colorless to slight yellow clear liquid. It possesses a characteristic chemical structure that makes it a valuable reagent. Key specifications often include a high purity level, commonly ≥99.0%, ensuring its effectiveness in precise chemical reactions. Its stability is good under recommended storage conditions, which usually involve cool, ventilated environments, away from direct sunlight, heat, and moisture, often at temperatures around 0-6°C.

Understanding the Hazards

One of the primary hazards associated with Tert-Butyl Bromoacetate is its lachrymatory effect. This means it can cause irritation to the eyes, leading to tearing and discomfort. Therefore, working with this compound necessitates appropriate protective measures to prevent exposure. While less commonly encountered in everyday industrial use at typical exposure levels, high doses have been noted in some research contexts to raise concerns about potential health risks, underscoring the importance of minimizing exposure.

Safe Handling Practices in the Laboratory and Industry

Given its lachrymatory nature, safe handling of Tert-Butyl Bromoacetate is paramount. Best practices include:

  • Ventilation: Always handle the compound in a well-ventilated area, preferably within a fume hood. This is critical for dissipating any vapors and preventing inhalation or eye exposure.
  • Personal Protective Equipment (PPE): Essential PPE includes chemical-resistant gloves (such as nitrile or neoprene), safety goggles or a face shield, and a laboratory coat. Ensure that all PPE is in good condition and properly fitted.
  • Storage: Store Tert-Butyl Bromoacetate in its original, tightly sealed container in a cool, dark, and well-ventilated location, adhering to the manufacturer's recommended temperature range (e.g., 0-6°C).
  • Spill Management: In case of a spill, evacuate the immediate area and ensure adequate ventilation. Use appropriate absorbent materials and dispose of waste according to local regulations. Avoid direct contact with the spilled material.
  • First Aid: In case of eye contact, immediately flush with plenty of water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air. If ingested, do not induce vomiting; seek immediate medical attention.

Procurement and Reliability

When sourcing Tert-Butyl Bromoacetate (CAS 5292-43-3), it is crucial to purchase from reputable manufacturers and suppliers who provide comprehensive safety data sheets (SDS) and product specifications. Understanding these details ensures that you are equipped to handle the material safely and effectively in your research or production processes.
