What are its key applications?

1. ​Food Industry:
   • Acts as an acidity regulator (E260) in sauces, dressings, and pickled products
     1
     .
   • Enhances flavor and extends shelf life due to its antimicrobial properties

     .
2. ​Chemical Synthesis:
   • Raw material for producing vinyl acetate, acetic anhydride, and esters.
3. ​Aquaculture & Agriculture:
   • Used to adjust water pH in aquaculture and as a disinfectant against parasites like Ichthyophthirius multifiliis (white spot disease)

     .

What safety precautions are necessary?

• ​Corrosivity:
  • Causes severe skin burns and eye damage (UN No. 2789 for solutions >80%)
    1
    .
  • Use gloves, goggles, and ventilation when handling.
• ​Storage:
  • Store in acid-resistant containers (e.g., glass or polyethylene) below 25°C
    1
    .
  • Avoid contact with oxidizers (e.g., hydrogen peroxide) to prevent violent reactions
    2
    .
• ​Environmental Impact:
  • Biodegradable but requires neutralization before disposal to avoid ecosystem harm.
