Description

L-Aspartic Acid Potassium Salt is the potassium salt derivative of the essential amino acid L-aspartic acid. This compound is valued for its role as a bioavailable source of both potassium and aspartate, making it a key ingredient in specialized nutritional and pharmaceutical formulations. It is primarily utilized by manufacturers in the dietary supplement, clinical nutrition, and pharmaceutical industries seeking to develop products that support electrolyte balance and cellular metabolism.

Application

• Dietary Supplements & Nutraceuticals: Used as a bioavailable potassium source in electrolyte blends, sports nutrition products, and general wellness supplements.
• Pharmaceutical Intermediates: Serves as a key building block or counterion in the synthesis of active pharmaceutical ingredients (APIs) and diagnostic agents.
• Clinical & Enteral Nutrition: Incorporated into medical food and parenteral/enteral nutrition solutions to address potassium deficiency and support metabolic functions.
• Biochemical Research: Employed as a defined component in cell culture media, enzymatic reaction buffers, and microbiological growth media.
• Food Fortification: Potential use in functional food and beverage products designed for electrolyte replenishment, subject to regional regulatory approval.

Quality Control

Our L-Aspartic Acid Potassium Salt is produced under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for nutritional and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing parameters such as assay, optical rotation, heavy metals, and residual solvents. We can supply grades compliant with relevant pharmacopeial monographs (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed after opening to minimize exposure to atmospheric humidity.
