PYRUVIC ACID

Pyruvic acid is an organic acid with the chemical formula CH₃COCOOH, known for its role as an intermediate in metabolic pathways, such as glycolysis in living organisms. It is a colorless to light yellow liquid with a pungent vinegar-like odor. Pyruvic acid is highly versatile, used in industries like pharmaceuticals, cosmetics, food, and agriculture. Its reactivity as a keto acid makes it valuable for synthesizing numerous organic compounds.

Safety and Handling

• Hazards:
  • Pyruvic acid is corrosive and can cause severe irritation or burns to the skin, eyes, and respiratory tract.
  • Vapors are pungent and can be harmful if inhaled, causing irritation to the throat and lungs.
  • Ingestion may lead to gastrointestinal irritation and toxicity.
• Precautions:
  • Personal Protective Equipment (PPE): Wear gloves, safety goggles, and protective clothing when handling pyruvic acid.
  • Ventilation: Use in a well-ventilated area or under a fume hood to avoid inhalation of vapors.
  • Storage: Store in a tightly sealed container in a cool, dry, and well-ventilated place, away from strong oxidizers and heat sources.
  • Handling: Avoid direct contact with the liquid and prevent inhalation of vapors. Use appropriate tools to minimize exposure.
• First Aid:
  • Eye Contact: Rinse eyes immediately with plenty of water for at least 15 minutes. Seek medical attention.
  • Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing and seek medical help for persistent irritation.
  • Inhalation: Move the person to fresh air immediately. Seek medical assistance if symptoms like coughing, shortness of breath, or dizziness occur.
  • Ingestion: Rinse the mouth with water and seek immediate medical help. Do not induce vomiting.
