Sodium Propionate (CAS 137-40-6) is a widely recognized chemical compound with significant applications across several key industries. As a salt of propionic acid, this white crystalline solid plays a crucial role, particularly as a food preservative. For procurement managers and R&D scientists, understanding its properties, uses, and how to source it effectively is vital.

What is Sodium Propionate?
Sodium Propionate is an organic sodium salt with the chemical formula Na(C2H5COO). It presents as a white crystalline powder, often characterized by its hygroscopic nature and solubility in water. Its primary function in the food industry is its potent ability to inhibit the growth of mold and other microorganisms, thereby extending the shelf life of various food products. In Europe, it is identified by the E number E281.

Key Applications:

• Food Preservation: This is perhaps the most well-known application. Sodium Propionate is extensively used in baked goods, such as bread, cakes, and pastries, to prevent mold formation. It is also found in other processed foods, including cheeses, dried fruits, and even some beverages. Its effectiveness at low concentrations makes it a cost-efficient choice for food manufacturers.
• Bakery Industry: The bakery sector relies heavily on Sodium Propionate to maintain the quality and freshness of its products. Its ability to suppress fungal growth is critical in preventing spoilage and ensuring that baked goods reach consumers in optimal condition.
• Pharmaceutical Intermediate: Beyond its role as a food additive, Sodium Propionate serves as a valuable intermediate in the synthesis of certain pharmaceutical compounds. Its chemical structure makes it a useful building block for various drug formulations.
• Industrial Uses: While less common, Sodium Propionate can also find applications in other industrial processes requiring its specific chemical properties.

Procurement Considerations:
When sourcing Sodium Propionate, quality and reliability are paramount. As a buyer, you'll be looking for a trusted manufacturer or supplier that can guarantee the purity and consistency of the product. If you're searching for 'Sodium Propionate price,' engaging with suppliers who offer competitive rates without compromising on quality is key. Factors to consider include the supplier's production capacity, adherence to quality certifications (like ISO), and their logistical capabilities. Many global buyers choose to buy Sodium Propionate from China due to the favorable cost-benefit ratio offered by its manufacturers.

Finding a Sodium Propionate Supplier:
When you need to purchase Sodium Propionate, look for suppliers who can provide comprehensive documentation, including Certificates of Analysis (CoA) and Safety Data Sheets (SDS). Direct factory exporters often provide the best value and direct communication. Whether you need a small quantity for R&D or bulk orders for large-scale production, identifying a reliable manufacturer is the first step to success.

In summary, Sodium Propionate is a versatile chemical with indispensable applications. By understanding its uses and working with reputable suppliers, businesses can effectively leverage this important compound.
