Product Overview & Quality

Product Name: di-Sodium hydrogen phosphate anhydrous (Sodium phosphate dibasic)
Grade: Analytical Reagent (AR Grade), featuring high purity ( 99%) with strictly controlled trace impurities for sensitive biochemical applications.
Physical Properties: Odorless, white powder or granules.
Solubility: Soluble in water; forms a slightly alkaline solution (pH ~ 9.1).
Key Use: A primary component for preparing Phosphate Buffered Saline (PBS) and other biological buffers to maintain stable pH in cell culture and molecular biology.

Safety & Hazards

Classification: Generally recognized as safe (GRAS); non-hazardous under GHS criteria.
Health Risks: Dust may cause minor mechanical irritation to the eyes and respiratory tract. It exhibits very low acute toxicity.
First Aid Measures: Flush eyes with plenty of water. Move to fresh air if dust is inhaled.

Handling & Storage

Storage: Store in a cool, dry place in a tightly sealed container. The substance is hygroscopic and will readily absorb moisture from the air if left exposed, leading to caking or alteration of its anhydrous state.
Precautions: Wear standard PPE, including gloves and safety goggles. Prevent dust formation. Store away from strong oxidizing agents and strong acids.
