Product Overview & Quality

Product Name: Ortho-Phosphoric Acid (Phosphoric Acid)
Grade: Analytical Reagent (AR Grade), 2.5 L pack. Typically features 85% concentration. It is a high-purity reagent with strictly controlled trace levels of heavy metals, chlorides, and sulfates for precision laboratory use.
Physical Properties: Clear, colorless, odorless, and viscous (syrupy) liquid.
Solubility: Fully miscible with water and ethanol.
Key Use: Widely used for preparing phosphate buffers in molecular biology, pH adjustment in analytical assays, and as a reagent in mineral and metal analysis.

Safety & Hazards (Critical)

Classification: Corrosive (Category 1). Causes severe skin burns and serious eye damage.
Health Risks: Direct contact leads to immediate tissue damage. Although it lacks a strong odor, it remains a potent chemical hazard. Due to its viscosity, it tends to adhere to surfaces and skin longer than less viscous acids.
First Aid Measures: Immediately flush eyes or skin with plenty of flowing water for at least 15-30 minutes. Seek immediate medical attention for any exposure.

Handling & Storage

Storage: Store in a cool, dry, well-ventilated area in acid-resistant containers (HDPE or glass). Keep strictly away from strong bases, reactive metals, and oxidizing agents.
Precautions: Full PPE is mandatory, including chemical-resistant gloves and safety goggles. Handle with care, as its syrupy consistency can make spills more difficult to neutralize and clean.
