Description

Sodium Glycerophosphate Hydrate is an organophosphate salt that serves as a vital source of bioavailable phosphorus and sodium. This compound is valued for its stability and solubility, making it a preferred ingredient in formulations requiring controlled nutrient delivery. It is essential for manufacturers in the pharmaceutical, nutraceutical, and advanced food fortification industries seeking a high-purity, reliable phosphate source.

Application

• Pharmaceutical Formulations: Used as an excipient and a source of phosphate and sodium in intravenous (IV) solutions, total parenteral nutrition (TPN), and electrolyte-replenishing products.
• Dietary Supplements & Nutraceuticals: Incorporated into mineral supplements, capsules, and liquid tonics to support bone health, energy metabolism, and cellular function.
• Food & Beverage Fortification: Acts as a nutritional additive in functional foods, sports drinks, and infant formula to enhance mineral content.
• Cell Culture Media: Serves as a component in specialized microbiological media and buffer systems for biopharmaceutical production and research.
• Cosmetic & Personal Care: Utilized in certain skincare products for its buffering capacity and potential skin-conditioning properties.
• Biochemical Research: Employed as a reagent in enzymatic studies and biochemical assays requiring phosphate buffers.

Quality Control

Our Sodium Glycerophosphate Hydrate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for assay, heavy metals, residual solvents, and microbiological parameters are available upon request. We can supply grades suitable for various applications, including those manufactured in alignment with cGMP principles.

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 immediately after use to minimize exposure to atmospheric moisture, which can lead to caking or degradation.
