Product Overview & Quality

Product Name: di-Sodium hydrogen phosphate dihydrate (Disodium phosphate dibasic dihydrate)
Brand: Kemaus (Product Code: KA-3966)
Grade: Laboratory Grade (Lab Grade) with a dependable purity of 98 percent or higher. Manufactured under Kemaus standard laboratory quality control protocols to guarantee premium physical uniformity and consistent chemical properties. Containing only two molecules of crystalline water, it offers superior structural stability and is much less prone to efflorescence compared to the dodecahydrate form. Excellently suited for academic science experiments, routine solutions preparation, and general chemical analysis.
Physical Properties: Odorless, fine white crystalline powder or small white granular crystals. Highly stable under ambient air conditions.
Solubility: Highly soluble in water (solubility increases substantially in warm water); practically insoluble in alcohol. Yields a mildly alkaline aqueous solution.
Key Use: Widely utilized as a primary compound paired with sodium dihydrogen phosphate for preparing accurate Phosphate Buffer Solutions to maintain stable physiological pH baselines (typically within the pH 6.5 to 8.0 window) across biochemistry and microbiology setups. Commonly applied in formulating standard biological culture media, and functions as an effective pH regulator or stabilizing agent in environmental water testing and general chemical precipitation assays.

Safety & Hazards

Classification: Not classified as a dangerous substance according to GHS regulations. It presents a highly stable chemical profile with low toxicity. Acts as a mild physical and mechanical dust irritant.
Health Risks: Direct eye contact with fine dust triggers temporary mechanical irritation, watering, and minor redness. Prolonged skin contact may cause slight localized dryness. Inhalation of airborne particles may induce coughing or sneezing.
First Aid Measures: Flush eyes or skin immediately with plenty of flowing water for at least 15 minutes. Seek medical evaluation if irritation develops or persists.

Handling & Storage

Storage: Mildly Hygroscopic. It can slowly absorb ambient moisture from high-humidity environmental air, which may cause physical caking or clumping over time. Must be stored in its original, tightly sealed Kemaus container. Keep in a cool, dry, and well-ventilated space at stable room temperature (below 30 degrees Celsius). Keep container tightly capped immediately after each use.
Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a particulate dust mask. Avoid leaving the bulk chemical exposed to open atmospheric air for prolonged intervals.
