For professionals in the chemical procurement and R&D sectors, a thorough understanding of the compounds they source is essential. Ammonium alginate (CAS 9005-34-9) is a prime example of a versatile ingredient with widespread applications, primarily derived from marine algae. This guide aims to provide comprehensive insights into its chemical nature, production, and critical uses, enabling buyers to make informed purchasing decisions.

Chemically, ammonium alginate is the ammonium salt of alginic acid, a natural polysaccharide composed of repeating uronic acid units. Its molecular formula, (C6H7O6NH4)n, indicates its composition. Typically appearing as a white to light yellow fibrous or granular powder, it is almost odorless and tasteless. Its most notable characteristic is its solubility in water, forming a viscous, sticky solution. Conversely, it is insoluble in ethanol, chloroform, and acidic solutions with a pH below 3. This solubility profile dictates its utility in various formulations. When considering purchasing ammonium alginate, understanding these solubility characteristics is crucial for application development.

The production of ammonium alginate involves extracting alginic acid from brown seaweed, followed by neutralization with ammonium hydroxide. Manufacturers strive for high purity and specific viscosities to meet diverse customer needs. For those looking to buy ammonium alginate, inquiring about the manufacturer's production processes and quality control measures is advisable. Many suppliers in China offer competitive pricing for bulk orders, making it an accessible ingredient for many industries.

The applications of ammonium alginate are extensive. In the food industry, it serves as a thickening agent, stabilizer, and gelling agent in products like jams, jellies, and dairy desserts. Its ability to enhance texture and stability makes it a valuable component for food technologists. In the pharmaceutical realm, it acts as an excipient in tablet formulations, aiding in binding and film formation. Research scientists often seek specific grades that meet USP, BP, EP, or FCC standards. For industrial uses, it functions as a sizing agent in textiles and a binder in welding rods.

When sourcing ammonium alginate, buyers should consult product specifications carefully. Key parameters include appearance, viscosity, pH, and loss on drying. Engaging with reputable suppliers who can provide detailed technical data sheets (TDS) and safety data sheets (SDS) is essential. Exploring wholesale ammonium alginate options from trusted manufacturers will ensure you acquire a high-quality product that meets your exact requirements.
