Brilliant Blue FCF, scientifically known as Erioglaucine Disodium Salt (CAS 3844-45-9), is a synthetic organic dye of significant commercial importance across multiple industries. Its distinctive vibrant blue color, coupled with excellent stability and solubility, makes it a preferred choice for manufacturers. This article provides a comprehensive look at its properties, diverse applications, and crucial considerations for B2B buyers looking to source this essential chemical.

The chemical identity of Brilliant Blue FCF is characterized by its molecular formula C37H34N2Na2O9S3 and a molecular weight of approximately 792.85 g/mol. Its appearance is typically described as a red-purple to blue-purple powder or granule. A key specification for quality is its assay, which is generally required to be ≥85%. This high purity ensures consistent performance and vibrant coloration in end products. When researching manufacturers or suppliers, these specifications are vital for ensuring you procure a product that meets your exact needs.

The utility of Brilliant Blue FCF spans several sectors. In the food industry, it is widely used as a food coloring agent (INS No. 133, E133) to enhance the visual appeal of products such as confectionery, beverages, dairy items, and baked goods. Its ability to be combined with other food-grade colorants allows for the creation of a broad spectrum of colors. For pharmaceutical applications, it acts as a coloring agent in medicines, aiding in product identification and patient safety. The cosmetic industry also leverages its vibrant hue for use in personal care products like shampoos, soaps, and makeup. When looking to buy Brilliant Blue FCF, consider its intended application to ensure the correct grade is selected.

Beyond consumer products, Brilliant Blue FCF has found niche applications in industrial settings, notably as a water tracer dye. Its stability and distinct color make it effective for tracking water flow and identifying potential leaks or contamination pathways in environmental studies and engineering projects. For industrial buyers, sourcing in bulk from a reliable manufacturer is often the most cost-effective strategy.

When sourcing Brilliant Blue FCF, B2B procurement professionals should focus on several key aspects. Firstly, identify reputable manufacturers and suppliers who can consistently provide the required specifications (e.g., ≥85% assay). Secondly, inquire about pricing for bulk orders, as this is often where significant cost savings can be realized. Thirdly, ensure that the supplier can provide necessary documentation, such as Certificates of Analysis (CoA) and Safety Data Sheets (SDS), which are critical for regulatory compliance and quality control. We, as a manufacturer, are committed to providing high-quality Brilliant Blue FCF with transparent documentation to support your procurement needs.

In conclusion, Brilliant Blue FCF is a versatile and essential synthetic dye with a broad range of applications.
