Description

Glycerophosphoric Acid CAS NO 57-03-4 is an important organophosphorus compound that serves as a key intermediate and functional ingredient in advanced chemical synthesis. This versatile acid is valued for its ability to introduce phosphate groups into molecules, modifying their properties for specialized applications. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries for producing phospholipids, emulsifiers, and bioactive compounds.

Application

• Pharmaceutical Intermediate: Critical for the synthesis of phospholipids and other active pharmaceutical ingredients (APIs) where phosphate ester linkages are required.
• Nutraceutical Production: Used in the manufacture of dietary supplements and functional food ingredients, such as choline alfoscerate and other cognitive health compounds.
• Biochemical Research: Serves as a reagent and building block in life science research for studying cell membrane biology and signal transduction pathways.
• Specialty Surfactants & Emulsifiers: Acts as a precursor for producing high-performance, biodegradable surfactants with specific hydrophilic-lipophilic balance (HLB) properties.
• Cosmetic Formulations: Employed in advanced skincare products for its role in creating skin-identical lipids and delivery systems.
• Metal Chelation & Corrosion Inhibition: Finds application in industrial water treatment and metal surface treatment formulations.

Quality Control

Our Glycerophosphoric Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the high-purity standards required for pharmaceutical and nutraceutical applications. We provide detailed Certificates of Analysis (COA) with key parameters including assay, identity, and impurity profiles, ensuring full traceability and compliance with relevant industry guidelines.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and stability.
