Description

Dipotassium Sodium Pyrophosphorate is a high-purity inorganic salt with significant industrial utility. Its primary value lies in its role as a stable and effective source of pyrophosphate ions, which are crucial for various chemical and manufacturing processes. This compound is essential for industries requiring precise buffering, sequestering, or emulsifying agents, such as specialty chemical synthesis, water treatment, and certain food processing applications.

Application

• Food Additive (Emulsifier & Buffer): Used as a stabilizer and pH regulator in processed foods, particularly in cheese and meat products.
• Water Treatment Agent: Acts as a sequestrant and corrosion inhibitor in boiler and cooling water systems to control scale formation.
• Industrial Detergent Formulation: Serves as a builder and water softener in heavy-duty cleaning and degreasing compounds.
• Ceramic & Electroplating: Employed in electroplating baths and ceramic glazes for its metal-chelating properties.
• Pharmaceutical Intermediate: Used in the synthesis of certain pharmaceutical compounds requiring pyrophosphate chemistry.
• Laboratory Reagent: Functions as a buffering agent and standard in analytical chemistry and biochemical research.

Quality Control

Our Dipotassium Sodium Pyrophosphorate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets high-purity standards, with typical grades conforming to Food Chemical Codex (FCC) or technical specifications as required. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
