Description

Potassiumisocitrate is a potassium salt of isocitric acid, a key intermediate in the citric acid cycle. This compound is valued for its role as a buffering agent and a source of bioavailable potassium in specialized formulations. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and food ingredient industries seeking a functional organic acid salt. Its properties make it suitable for applications requiring precise pH control and metabolic activity.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as an excipient in electrolyte-balancing formulations.
• Nutraceutical & Dietary Supplements: Serves as a source of potassium in mineral supplements and functional beverage powders.
• Food & Beverage Industry: Acts as an acidity regulator, stabilizer, and sequestrant in certain food systems and health drinks.
• Biochemical Research: Employed as a substrate or standard in enzymatic studies related to the Krebs cycle and metabolic pathways.
• Cosmetic Formulations: Can be used in skincare products for its buffering capacity and potential skin-conditioning properties.
• Industrial Biotechnology: Potentially used in fermentation media and as a component in specialized buffer solutions.

Quality Control

Our Potassiumisocitrate is produced and tested under a strict quality management system. We offer grades suitable for various applications, with specifications that can meet general industrial or more stringent requirements. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to ensure traceability and batch-to-batch consistency.

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 tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
