Description

Bismuth Citrate is a high-purity, inorganic salt of bismuth and citric acid, widely recognized for its unique chemical and physical properties. This compound is essential for applications requiring a reliable source of bismuth with good solubility characteristics in specific matrices. It serves as a critical raw material for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries, where consistent quality and supply chain integrity are paramount. Its utility spans from active pharmaceutical ingredient (API) synthesis to advanced material formulation.

Application

• Pharmaceutical Intermediates: Used in the synthesis of bismuth-containing active pharmaceutical ingredients (APIs) for gastrointestinal treatments.
• Cosmetic & Personal Care: Acts as a pearlescent agent or opacifier in high-end lipsticks, nail polishes, and other color cosmetics.
• Catalyst Systems: Serves as a precursor or component in catalysts for organic synthesis and polymerization reactions.
• Analytical Reagents: Employed as a standard or reagent in analytical chemistry for quality control and research laboratories.
• Specialty Chemicals: Functions as an additive in lubricants, coatings, and other industrial formulations requiring specific metal ion properties.
• Research & Development: Utilized in academic and industrial R&D for developing new materials and chemical processes.

Quality Control

Our Bismuth Citrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for purity, identity, and heavy metal content. We provide full traceability and support our products with Certificates of Analysis (COA) upon request, confirming compliance with relevant standards. Our quality commitment ensures reliability for your most demanding applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
