Eosin Blue is a synthetic azo dye identified by CAS No. 548-24-3 and CI No. 45400. Its molecular formula is C20H6Br2N2Na2O9 with a molecular weight of 624.09 g/mol. The supplier reports a dye content greater than 85% by gravimetry, indicating a high proportion of active colourant in the material.
The dye dissolves at 0.1% in distilled water, forming a clear solution suitable for analytical work. Its absorption maximum lies between 516 and 520 nm, and the absorptivity exceeds 800 L·mol⁻¹·cm⁻¹ at this wavelength, providing strong colour intensity. Typical purity for laboratory dyes of this class is analytical grade (≥99%) and they are usually stored in a cool, dry environment away from direct sunlight.
Eosin Blue is commonly used for histological staining, fluorescence microscopy and certain pharmaceutical assays, making it attractive to research laboratories and contract testing facilities. The supplier can provide bulk packaging, but exact minimum order quantities and incoterms must be confirmed directly. Buyers should also verify payment terms and any required safety data sheets before finalising the purchase.

Before placing an order, verify the supplier’s legal registration, import licences and the authenticity of any quality certificates they provide. Request a recent safety data sheet and a certificate of analysis for the specific batch to ensure compliance with your destination country’s regulations.
Discuss logistics early: confirm the preferred Incoterm (FOB, CIF or others), shipping method, and any special handling requirements for hazardous chemicals. While the supplier does not list lead times, ask for an estimated production and dispatch schedule, and clarify accepted payment terms such as T/T or LC.
Arrange a third‑party inspection if possible, focusing on dye content, purity and loss on drying. Ensure the inspection report references the relevant test methods (e.g., gravimetric analysis, UV‑Vis spectroscopy) and that all documentation, including the SDS, accompanies the shipment.
