For procurement professionals and R&D scientists in the chemical industry, grasping the detailed specifications of ingredients like Sunset Yellow FCF (CAS 2783-94-0) is fundamental to making informed purchasing decisions. As a leading manufacturer and supplier, we believe in transparency regarding our product's characteristics to ensure our B2B clients can confidently integrate it into their formulations.

When you buy Sunset Yellow FCF, the first aspect to scrutinize is its appearance and basic properties. Our product is consistently described as an Orange Red Powder, indicative of its high purity and quality. Beyond visual cues, critical specifications often include the color and lustre, which should be a vibrant orange-red. This ensures the dye performs as expected in imparting the desired hue to food, cosmetic, or pharmaceutical products.

A key specification that sets a premium product apart is its concentration or dye content, typically measured as ≥87.0%. This parameter directly affects the efficacy and color intensity achieved in the final product. Another crucial aspect is the moisture content, often reflected in the 'dry decrement' value, which should be within acceptable limits (e.g., ≤13.0% w/w) to ensure product stability and shelf life. As a reputable manufacturer, we meticulously control these parameters.

Furthermore, the presence of impurities is a significant concern, particularly for food and pharmaceutical applications. Specifications for water-insoluble matter (≤0.20% w/w) and specific organic impurities like sodium p-aminobenzenesulfonate (≤0.20% w/w) and sodium 6-hydroxynaphthalene-2-sulfonate (≤0.30% w/w) are vital. Limits on heavy metals such as Arsenic (As) (≤1.0 mg/kg) and Lead (Pb) (≤10.0 mg/kg) are also critical for safety compliance. When sourcing from a supplier in China, verifying adherence to these strict limits is paramount.

Understanding these specifications helps buyers make informed comparisons and select the best price point that aligns with their quality requirements. For those looking to purchase Sunset Yellow FCF, working with a manufacturer that provides a detailed Certificate of Analysis (CoA) for each batch is standard practice. This document serves as proof that the product meets the agreed-upon specifications.

In essence, a thorough understanding of Sunset Yellow FCF specifications empowers B2B customers to select the right product for their needs and to evaluate suppliers effectively. As a committed supplier, we ensure our product meets these exacting standards, providing a reliable foundation for your product development and manufacturing processes.
