Description

Magnesium Succinate n-Hydrate is a high-purity, organically bound magnesium salt of succinic acid. This compound is valued for its superior bioavailability and stability compared to inorganic magnesium sources, making it an essential ingredient in advanced nutritional and pharmaceutical formulations. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and specialty chemical industries for applications requiring a highly soluble and bioavailable magnesium source.

Application

• Nutraceutical & Dietary Supplements: As a premium source of bioavailable magnesium in capsules, tablets, and powder blends for bone health, muscle function, and energy metabolism support.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) where the succinate moiety or magnesium ion is pharmacologically active.
• Food & Beverage Fortification: Employed as a mineral fortifier in functional foods and beverages, offering a neutral flavor profile and excellent solubility.
• Cosmetic & Personal Care: Incorporated into skincare products for its potential skin-soothing and anti-inflammatory properties.
• Biochemical Research: Serves as a reagent or buffer component in enzymatic studies and cell culture media preparation.
• Industrial Catalysts & Additives: Acts as a precursor or catalyst in specific organic synthesis and polymer production processes.

Quality Control

Our Magnesium Succinate n-Hydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for purity, identity, and heavy metal content. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, loss on drying, and residual solvents. Our quality commitment supports compliance with cGMP, FCC, and USP guidelines for relevant applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking. Keep away from incompatible materials.
