Product Overview & Quality

Product Name: di-Potassium hydrogen phosphate (Dipotassium phosphate dibasic)
Brand: Kemaus (Product Code: KA-2221)
Grade: Analytical Reagent (AR Grade) with a premium purity of 99 percent or higher. Meticulously manufactured and verified under Kemaus strict laboratory quality control standards to ensure exceptionally low trace levels of heavy metals, chlorides, and sulfates, providing a highly reliable chemical baseline for analytical and biochemical applications.
Physical Properties: Odorless, fine white crystalline powder or granular crystals. Highly soluble in aqueous solutions.
Solubility: Extremely soluble in water (solubility increases substantially in warm water); slightly soluble in alcohol. Yields a mildly alkaline aqueous solution.
Key Use: Heavily utilized as a primary compound paired with potassium dihydrogen phosphate for preparing standard Potassium Phosphate Buffer Solutions. These buffers are widely used across biochemistry, molecular biology, and microbiological laboratories to maintain stable biological pH baselines (typically within the pH 6.5 to 8.0 window). Commonly applied as an essential nutrient source of potassium and phosphorus in formulating specialized biological culture media, and functions as an effective reagent for analytical chemical assays and industrial R&D.

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: Hygroscopic material. It easily absorbs ambient moisture from environmental air, which alters its physical form and causes chemical caking or severe 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 volumetric dispensing.
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.
