Evan's Blue supplied by Karan Labortes is a synthetic triphenylmethane dye identified by CAS No 314‑13‑6 and CI No 23680. The molecular formula C34H24N6Na4O14S4 gives a molecular weight of 960.82 g mol⁻¹. Supplier data show a dye content exceeding 85 % by spectrophotometry. The dye dissolves in water to a clear solution at 0.1 % (w/v) and exhibits an absorption maximum between 605 nm and 611 nm. Its absorptivity at the peak is greater than 800 L g⁻¹ cm⁻¹ and the loss on drying at 110 °C is reported as low.
Such optical characteristics place Evan's Blue in the standard analytical grade used for histological staining and dye‑based assays. Typical industry practice expects a purity above 80 % and compliance with ISO 9001 quality management, which aligns with the >85 % content reported. The dye is normally supplied as a dry powder and should be stored in moisture‑controlled conditions to preserve colour stability. Standard packaging for bulk chemical trade includes typical 25 kg HDPE drums sealed with inner liners.
Buyers in pharmaceutical research, biotechnology and textile laboratories import this colourant for staining protocols and specialty colouring. Karan Labortes can ship in 25 kg HDPE drums and is prepared to discuss FOB Mumbai or CIF European ports, while exact minimum order quantities and lead times must be confirmed with the supplier. Importers should obtain a current safety data sheet and certificate of analysis to verify compliance before placing an order.

Before placing an order, request the latest safety data sheet and a certificate of analysis that confirms the CAS number, dye content and loss on drying. Verify that the supplier can provide any required regulatory documentation for your target market, such as REACH registration or GHS classification, if applicable.
Logistics should be clarified with Karan Labortes: confirm whether the shipment will be FOB from Mumbai Port or CIF to your destination, and ask for an estimated lead time based on current production schedules. Discuss preferred freight options, container loading plans and any special handling requirements for hazardous chemicals, even though Evan's Blue is generally classified as non‑hazardous under normal quantities.
Arrange for a pre‑shipment inspection or third‑party laboratory testing to validate purity and colour performance. Request documentation of the inspection, including test reports for dye content, absorptivity and moisture level. Align payment terms and insurance coverage with the agreed Incoterms to protect against transit risks.
