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 that decomposes cleanly upon heating. It is primarily sought after by manufacturers in the food, pharmaceutical, and specialty chemical sectors for its unique functional properties.

Application

• Food Industry: As a leavening agent in baked goods like cookies and crackers, and as a pH regulator.
• Pharmaceuticals: Used as an active ingredient in expectorants and smelling salts, and as a buffering agent.
• Laboratory & Analytical Chemistry: Serves as a reagent for qualitative inorganic analysis and in buffer solutions.
• Textile & Leather Processing: Employed in dyeing and printing processes, and for deliming hides.
• Fire Extinguishers: A component in certain dry chemical fire extinguishing compounds.
• Flotation Agents: Used in mineral processing for ore separation.
• Photography: Historically used in developing and toning solutions.
• Fertilizer & Agriculture: Provides a readily available source of nitrogen for plant nutrition.

Quality Control

Our Ammonium Carbonate is produced and tested to meet stringent quality standards suitable for its target applications, including Food Grade (FCC) and Technical Grade specifications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles. We ensure compliance with relevant industry and regulatory guidelines to guarantee supply reliability and product consistency for our global B2B partners.

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) and highly volatile nature, the container must be kept tightly sealed after each use to prevent moisture absorption, caking, and loss of ammonia. Keep away from heat and incompatible materials such as strong acids.
