Description

Ammonium Carbonate is a versatile inorganic salt widely recognized for its role as a leavening agent and pH adjuster. This compound is crucial for industries requiring a source of ammonia and carbon dioxide upon decomposition, offering a clean and efficient reaction profile. Key sectors that rely on this material include food manufacturing, pharmaceuticals, and specialty chemical synthesis. Its consistent quality and reliable performance make it a fundamental ingredient for numerous industrial processes.

Application

• Food Industry: Primarily used as a leavening agent (baking powder) in flat baked goods like cookies and crackers, where rapid gas release is needed.
• Pharmaceuticals: Employed as an active ingredient in expectorants and cough syrups (e.g., aromatic ammonia spirit) and as a pH buffer in various formulations.
• Chemical Synthesis: Serves as a precursor and a source of ammonia in the manufacture of other ammonium salts, catalysts, and specialty chemicals.
• Laboratory & Analytical Chemistry: Used as a reagent for qualitative inorganic analysis and in buffer solutions.
• Textile & Leather Processing: Functions in dyeing and finishing processes as a pH regulator and cleaning agent.
• Fire Extinguishers: A component in some dry chemical fire extinguishing compounds.
• Photography: Historically used in developing solutions.
• Fertilizer & Agriculture: Provides a readily available source of nitrogen for plant nutrition in specific formulations.

Quality Control

Our Ammonium Carbonate is produced and tested to meet stringent quality standards, including FCC (Food Chemicals Codex) and technical grade specifications. Every batch undergoes rigorous analytical testing to ensure purity, identity, and performance consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical parameters is available for each shipment to guarantee compliance with your specific requirements.

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 and highly volatile nature, the container must be kept tightly sealed after each use to minimize exposure to moisture and prevent decomposition and ammonia loss.
