Basic Brown 4, also known as Bismark Brown R, is a synthetic basic dye with the chemical formula C21H26Cl2N8 and CAS number 5421-66-9. This powdered dyestuff is produced in Gujarat, India, and is used across multiple industries, including food, ink, paper, and textiles, where it provides a consistent brown colouration.
The dye’s molecular structure allows for strong affinity to acidic substrates, making it suitable for applications such as leather dyeing, paper staining, and textile printing. Typical dye content in commercial grades ranges from 85% to 95%, with the remainder comprising inert salts and moisture. Standard industry tests for purity include HPLC and spectrophotometry.
Textile manufacturers often use Basic Brown 4 for dyeing cotton, wool, and silk, while its stability in acidic conditions makes it a preferred choice for paper and ink formulations. Buyers should confirm the dye’s solubility, lightfastness, and heat resistance for their specific application, as these properties can vary based on the substrate and processing conditions.

Before placing an order, verify the dye’s purity, solubility, and suitability for your intended application. Request a certificate of analysis (COA) and, if applicable, safety data sheets (SDS) to ensure compliance with your industry’s regulatory requirements, such as FDA or REACH standards.
Confirm logistics details, including the Incoterms (e.g., FOB Ahmedabad), port of shipment, and preferred mode of transport. Basic Brown 4 is typically shipped in 25 kg or 50 kg bags, so discuss packaging options and any special handling requirements to prevent contamination or moisture exposure during transit.
Quality checks should include testing for dye content, solubility, and colour consistency using standard industry methods like HPLC. Inspect the packaging for damage upon arrival, and store the dye in a controlled environment to maintain its stability. Request documentation such as test reports and compliance certificates before finalising the order.
