Description

Ammonium Bismuth Citrate is a specialized inorganic-organic coordination compound that combines bismuth with citrate and ammonium ions. This unique composition provides enhanced solubility and bioavailability compared to many other bismuth salts, making it a valuable precursor in advanced material synthesis and pharmaceutical research. It is primarily utilized by manufacturers and R&D laboratories in the pharmaceutical, catalyst, and specialty chemical sectors seeking a reliable source of high-purity, soluble bismuth.

Application

• Pharmaceutical Intermediate: Serves as a key starting material or catalyst in the synthesis of novel bismuth-containing active pharmaceutical ingredients (APIs), particularly for gastrointestinal and antimicrobial applications.
• Catalyst Precursor: Used in the preparation of heterogeneous and homogeneous catalysts for organic synthesis and polymerization reactions.
• Material Science: Acts as a bismuth source for depositing thin films, creating bismuth-doped nanomaterials, and synthesizing functional ceramics and glasses.
• Analytical Reagent: Employed as a standard or reagent in analytical chemistry for the qualitative and quantitative determination of other substances.
• Research & Development: Utilized in academic and industrial R&D for exploring new chemical entities, coordination chemistry, and the properties of bismuth complexes.

Quality Control

Our Ammonium Bismuth Citrate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with key parameters such as assay (Bismuth content), heavy metal limits, and loss on drying. Specifications can be aligned with customer requirements for research or cGMP manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking or decomposition. Keep away from incompatible materials.
