Direct Brown 2, with CAS number 2429-82-5 and EINECS 219-391-6, is a diazo-based direct dye formulated for cotton, wool, and paper applications. Its chemical structure, C29H19N5Na2O7S, enables strong affinity for cellulosic and protein fibers, delivering a consistent brown hue with moderate to good washfastness. The dye is manufactured using controlled diazotization and coupling reactions in compliance with standard industrial practices.
The product is supplied as a fine powder with typical purity above 85% and moisture content under 6%. It dissolves readily in warm water and exhibits good stability in neutral to slightly alkaline conditions. While the listing references ISO certification, no certificate number or scope is provided. No data on heavy metal content or dyeing performance metrics such as lightfastness or rubbing fastness is included.
This dye is primarily used in textile dyeing for cotton blends and in paper manufacturing for packaging and decorative substrates. Buyers in the low-cost textile and printing industries rely on it for economical coloring. Packaging is typically in 25kg or 50kg multi-wall paper bags. Trade terms such as FOB and T/T are mentioned in the listing but require direct confirmation with the supplier for exact conditions.

Sourcing Direct Brown 2 from Tianjin Shenyuan Chemical Co., Ltd - China Import Guide
Before ordering Direct Brown 2 from Tianjin Shenyuan Chemical Co., Ltd, verify the EINECS and CAS numbers match the batch and request a Certificate of Analysis that includes purity, moisture, and heavy metal limits. Do not accept claims of ISO certification without the certificate number and scope. Confirm the dye’s compliance with local chemical regulations in your importing country.

Confirm minimum order quantity and whether samples are available. Payment methods such as T/T or LC should be negotiated in writing before shipment.
Upon receipt, inspect packaging for moisture damage and verify the batch label against the Certificate of Analysis. Conduct a solubility test and shade comparison against a reference sample under daylight. Retain a sample from each shipment for quality traceability. Request a GHS-compliant Safety Data Sheet and confirm it includes all hazard classifications.
