Description

Citric Acid, Monohydrate USP

Citric Acid, Monohydrate USP is a high-purity organic acid widely used in pharmaceutical, nutraceutical, food, and cosmetic formulations as an acidulant, buffering agent, chelating agent, and stabilizer. Compliant with United States Pharmacopeia (USP) standards, it provides reliable pH control, excellent solubility, and consistent performance across a broad range of applications.
Citric Acid, Monohydrate appears as colorless or white crystalline granules or powder with a pleasant acidic taste. It is freely soluble in water and slightly soluble in alcohol. The monohydrate form contains one molecule of water of crystallization, which contributes to its stability and ease of handling in both dry and liquid formulations.
In pharmaceutical, nutritional, food, and cosmetic applications, Citric Acid, Monohydrate USP is used in:
• Oral solutions, syrups, and liquid dosage forms as a pH adjuster
• Effervescent tablets and powders requiring controlled acid–base reactions
• Buffer systems for injectables, ophthalmic, and pediatric formulations
• Chelation of trace metal ions to improve active ingredient stability
• Flavor enhancement and preservation in foods and beverages
• Cosmetic and personal care formulations requiring mild acidity control
Citric Acid, Monohydrate USP enhances formulation stability by binding metal ions that may catalyze oxidative or hydrolytic degradation. It also improves taste, solubility, and bioavailability of many active pharmaceutical ingredients and nutrients.
Citric Acid, Monohydrate USP is supplied with control over assay, purity, water content, heavy metals, and microbial quality. The material meets USP monograph specifications and is suitable for regulated pharmaceutical, food, and cosmetic manufacturing.
The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in laboratory, pilot, and commercial-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and full traceability.
Each batch is tested for identity (IR), assay, water content, sulfate and oxalate impurities, heavy metals, and microbial limits. Technical support is available to assist with formulation optimization and regulatory compliance.
As a widely used multifunctional excipient, Citric Acid, Monohydrate USP supports safe, effective, and stable product development across pharmaceutical, nutritional, and consumer applications.
