Main Applications
Organic Synthesis
Halogenating Agent:
Converts alcohols (R-OH) to bromides (R-Br) with mild conditions and high yield, superior to hydrobromic acid.
Reacts with carboxylic acids (R-COOH) to form acyl bromides (R-COBr), used in synthesizing anhydrides, esters, or amides.
Brominates phenolic compounds.
Catalyst: Acts as a Lewis acid catalyst in condensation or cyclization reactions.
Pharmaceutical and Pesticide Industries
Used in synthesizing drug intermediates (e.g., antibiotics, hormones) and pesticides (e.g., insecticides, herbicides).
Analytical Chemistry
As a reagent for determining the content of alcohols, carboxylic acids, etc.
Safety and Storage
Hazards
Health Risks:
Highly corrosive; causes severe burns on skin/eye contact. Inhalation irritates the respiratory tract, leading to coughing, dyspnea, or pulmonary edema.
Ingestion corrodes the digestive tract, causing vomiting and abdominal pain.
Environmental Risks: Hydrolyzes to form HBr, a strong acid that pollutes water and soil.
Explosion Risk: Non-flammable but reacts violently with water/acids, potentially causing fire or explosion hazards.
Safety Protections
Personal Protective Equipment (PPE): Wear corrosion-resistant gloves, goggles, and a respirator (or gas mask); use protective clothing.
Emergency Measures:
For leaks, cover with dry sand, avoid water contact, and transfer to a sealed container with an explosion-proof pump.
For skin/eye contact, flush with plentiful water and seek medical attention immediately.
Storage Conditions
Store in a cool, dry, well-ventilated warehouse, away from fire sources and heat.
Separate from oxidizers, alkalis, alcohols, and food chemicals; do not mix storage.
Use corrosion-resistant containers (e.g., glass or Teflon); avoid metal containers.
