Citric Acid Anhydrous is a high-purity, colorless, or white crystalline powder. In Pharma Grade (conforming to USP/BP/EP standards), it is manufactured under strict quality controls to ensure it is free from elemental impurities and microbial contamination.
Unlike the monohydrate form, the anhydrous version contains no water molecules in its crystalline structure ($C_6H_8O_7$), making it the preferred choice for moisture-sensitive formulations.

Core Applications in Pharmaceuticals
• Effervescent Agent: It is most commonly used in combination with bicarbonates or carbonates to create the "fizz" in effervescent tablets and granules. This rapid reaction helps in the fast dissolution and absorption of active ingredients.
• pH Adjuster & Buffering Agent: Used to stabilize the pH of liquid medicines (syrups, drops, and injectables) to maintain the chemical stability of the active drug and ensure patient comfort during administration.
• Antioxidant Synergist: It enhances the effectiveness of other antioxidants by chelating trace metals that could otherwise catalyze the degradation of the medicine.
• Flavor Enhancer: Provides a clean, tart acidic taste that helps mask the bitter or medicinal aftertaste of various pharmaceutical syrups and chewable tablets.

Storage and Handling
Because it is anhydrous, it is highly hygroscopic (it attracts moisture from the air). It should be stored in a cool, dry place in airtight containers. If exposed to high humidity, it may cake or gradually convert to the monohydrate form, which can affect the precision of your chemical formulations.
