Liquid Basic Violet 10, universally known by its common name Rhodamine B, is a highly potent, water-soluble synthetic cationic xanthene dye. This liquid formulation is valued industrially for producing an intensely brilliant, reddish-violet (magenta) hue combined with powerful fluorescent properties that are highly visible even at low concentrations.
Key Technical Specifications
· Chemical Name: Rhodamine B / Rhodamine B Extra
· Color Index No.: C.I. Basic Violet 10 (C.I. 45170)
· CAS Number: 81-88-9
· Molecular Formula: C₂₈H₃₁ClN₂O₃
· Solubility: Highly soluble in both water and alcohol/ethanol.
· Fluorescence: Emits a vibrant, glowing bluish-red/pink light under UV illumination.
Common Applications
The stable liquid formulation eliminates dust pollution during manufacturing and is widely utilized by chemical processors across several sectors:
· Paper Industry: Primarily used for the heavy mass-dyeing of paper, glossy paper, cardboard, and recycled pulp mixtures.
· Inks & Writing Instruments: Serves as a core colorant for ballpoint pens, stamp pads, marker inks, and fluorescent printing inks.
· Water Flow Tracing: Employed as a highly visible tracer dye in environmental hydrology to track the rate and direction of water flow systems.
· Industrial Manufacturing: Used to provide uniform color to Medium-Density Fiberboard (MDF), acrylics, leather goods, and select textiles.
· Biotechnology: Utilized in laboratory research for fluorescence microscopy and cell organelle staining.
