• Boiling Point: 108.5 °C (227 °F) for a 20.2% solution
• Melting Point: −30 °C (−22 °F) for a 37% solution

• • Metal Pickling: Removes rust, scale, and oxides from iron or steel before processing.
  • Chemical Manufacturing: Serves as a primary reactant in producing vinyl chloride for PVC plastic, polyurethane, and calcium chloride.
  • Water Treatment: Adjusts pH levels in industrial wastewater, municipal water supplies, and swimming pools.
  • Food Processing: Hydrolyzes starch and proteins during the production of corn syrup and gelatin.
  • Ore Processing: Used in mining operations for crude ore extraction and metal refining. 

• High Reactivity: Dissociates completely in water to deliver rapid, efficient pH reduction and chemical transformations.
• Versatility: Available in multiple industrial and technical concentrations tailored to specific applications.
• Cost-Effective: Highly economical acid choice for large-scale industrial scale removal and neutralizing processes.

• • Hazard Class: Class 8 (Corrosive Substance)
  • Health Risks: Causes severe skin burns, permanent eye damage, and respiratory tract irritation if vapors are inhaled. [1]
  • Personal Protective Equipment (PPE): Mandates the use of chemical-resistant gloves (neoprene or nitrile), splash-proof safety goggles, a full face shield, and a vapor respirator in poorly ventilated areas. [1]
  • Storage: Store in a cool, dry, well-ventilated area away from strong oxidizing agents, bases, and reactive metals. Keep in original, corrosion-resistant UV-stabilized plastic containers.
