Description
Buy Citric Acid Monohydrate USP 99.5% | Food Grade Acidulant
High Purity Citric Acid for Pharmaceutical and Food Applications
Citric Acid Monohydrate (C₆H₈O₇·H₂O) is a naturally occurring tricarboxylic acid, commonly used as a flavor enhancer, acidulant, buffering agent, and chelator. This product is supplied in USP Grade with a purity of 99.5%, suitable for use in regulated pharmaceutical and food industry processes.
In pharmaceuticals, Citric Acid Monohydrate is widely used in oral formulations, effervescent tablets, and antacids, helping to adjust pH, enhance taste, and improve stability. It also functions as a chelating agent that binds metal ions in formulations, preventing degradation.
In food and beverages, it acts as a flavoring agent, preservative, and pH regulator, particularly in carbonated drinks, fruit products, jams, and confectionery. As a GRAS (Generally Recognized as Safe) substance, it is a preferred choice for food-grade formulations when you buy citric acid monohydrate from reliable suppliers.
Medical and Clinical Applications of USP Citric Acid
The compound is extensively used in cosmetics, cleaning agents, detergents, and biochemical research, where its high solubility and buffering capacity are valuable. Its crystalline structure, free-flowing texture, and mild acidic properties make it ideal for both manual and automated processes in industrial applications.
For medical applications, citric acid monohydrate serves as a critical component in electrolyte solutions and pharmaceutical formulations where precise pH control is essential. The National Institutes of Health recognizes citric acid as an important excipient in pharmaceutical manufacturing.
Storage and Stability Requirements
The product remains stable under dry, sealed conditions with a shelf life of 5 years, and should be stored away from moisture, alkalis, and incompatible materials. Proper storage ensures optimal performance for industrial and laboratory chemical applications.
