Overview
Basic Red, commonly known as Rhodamine B or Alkaline Red, is a synthetic dye belonging to the xanthene class. It is widely recognized for its vibrant red color and fluorescent properties under ultraviolet light. The dye is primarily used in industrial applications, including textile dyeing, ink manufacturing, and biological staining. Due to its stability in alkaline conditions, Basic Red is a preferred choice for applications requiring long-lasting color. However, its use in food and cosmetics is restricted in many countries due to potential health risks. The dye is typically supplied as a red to purple powder, soluble in water and ethanol.
Physical and Chemical Properties
Basic Red exhibits a molecular weight of 479.02 g/mol and a melting point of approximately 210-215°C. Its bright red color and fluorescence make it easily identifiable under UV light. The dye is highly soluble in water and ethanol, which facilitates its use in liquid formulations. The chemical stability of Basic Red in alkaline environments makes it suitable for textile dyeing processes where high pH conditions are common. However, it may degrade under prolonged exposure to strong acids or oxidizing agents. Its fluorescence properties are often utilized in biological staining and tracer applications.
Main Applications
Basic Red is extensively used in the textile industry for dyeing silk, wool, and cotton fabrics. Its vibrant hue and colorfastness make it a popular choice for producing bright red shades. In the printing industry, the dye is incorporated into inks for paper and plastic substrates. In biological laboratories, Basic Red serves as a staining agent for microscopy and flow cytometry. Its fluorescent properties enable researchers to track cellular components and processes. Additionally, the dye is employed as a tracer in environmental studies to monitor water flow and contamination.
Safety and Storage
Basic Red is considered a potential irritant to skin and eyes, necessitating the use of protective gloves and goggles during handling. Inhalation of dust particles should be avoided to prevent respiratory irritation. The dye should be stored in a cool, dry place, away from direct sunlight to maintain its stability. Disposal of Basic Red must comply with local environmental regulations, as it can be harmful to aquatic life. Spills should be contained and cleaned up promptly using appropriate absorbent materials. Always refer to the material safety data sheet (MSDS) for detailed safety instructions.
B2B Procurement Guide
When procuring Basic Red, B2B buyers should prioritize suppliers who provide detailed product specifications, including CAS number (81-88-9) and purity levels. Bulk purchases often come with cost advantages, but it's essential to verify storage requirements to prevent degradation. Quality assurance is critical; request certificates of analysis (CoA) to confirm the dye meets industry standards. Lead times and shipping conditions should also be considered, especially for international orders. Establish long-term relationships with reputable suppliers to ensure consistent quality and reliable delivery.
