Acid Blue 90 (CAS 6104-58-1), also known as Coomassie Brilliant Blue G-250, is a versatile synthetic dye widely recognized for its utility in both the scientific laboratory and industrial applications. Its distinct chemical properties, including its vibrant color and affinity for proteins and certain fibers, make it a valuable compound for a range of purposes. For businesses and researchers alike, understanding where and how to effectively source this chemical is key. As a dedicated manufacturer and supplier of fine chemicals, we provide a closer look at Acid Blue 90 and offer guidance on procurement.

Laboratory Excellence: Protein Quantification and Visualization

In research laboratories, Acid Blue 90 is a cornerstone reagent for protein analysis. Its application in the Bradford assay allows for the rapid and sensitive quantification of total protein concentration in biological samples. The assay relies on the dye's binding to proteins, which causes a color shift that can be measured spectrophotometrically. Similarly, it is used for staining proteins separated by gel electrophoresis techniques like SDS-PAGE, making the protein bands visible against a clear background. For these critical applications, purchasing high-purity Acid Blue 90 is essential to ensure accuracy and reproducibility. Researchers frequently buy this compound from specialized suppliers who guarantee quality specifications and consistent batch-to-batch performance.

Industrial Applications: Dyeing Textiles and Leather

Beyond the lab bench, Acid Blue 90 serves as an effective acid dye. Acid dyes are typically water-soluble anionic dyes used for dyeing materials containing basic groups, such as proteinaceous fibers (wool, silk) and synthetic polyamides (nylon). Acid Blue 90 imparts a desirable dark blue-violet-brown shade to these substrates. It is also utilized in the coloration of leather. Industrial users often require Acid Blue 90 in bulk quantities, making the choice of supplier crucial for both cost-effectiveness and supply chain reliability. Sourcing directly from manufacturers in China, known for their robust chemical production capabilities, can provide significant advantages in terms of pricing and availability.

Key Considerations When Purchasing Acid Blue 90

When you decide to buy Acid Blue 90, several factors should guide your selection:

  • Purity and Grade: Ensure the grade of Acid Blue 90 meets your specific application requirements, whether it's analytical grade for lab use or a suitable industrial grade for dyeing.
  • Supplier Reputation: Partner with reputable manufacturers or distributors known for quality products and reliable service. Look for suppliers who provide detailed product information and transparent dealings.
  • Competitive Pricing: For bulk purchases, competitive pricing is essential. Direct manufacturers often offer the best value.
  • Logistics and Delivery: Confirm that the supplier can manage efficient shipping and delivery to your location, whether domestic or international.
