Direct Red 16, identified as C.I. 27680 and CAS 6227-02-7, is a water-soluble azo dye used primarily for coloring cellulosic fibers such as cotton, viscose rayon, flax, and jute. It appears as a deep red powder and exhibits slight solubility in ethanol, yielding a peach-pink solution, while remaining insoluble in most organic solvents. The dye demonstrates a color shift in strong sulfuric acid, turning from blue to red and diluting to brown with a red precipitate, indicating its pH-sensitive chromophore structure.
This dye is formulated for applications requiring strong affinity to cellulose without mordants, making it suitable for direct dyeing processes in textile mills. Its molecular structure includes sulfonic acid groups that enhance water solubility and fiber bonding. Typical industry standards for Direct Red 16 include a minimum purity of 85% and a moisture content below 5%, though these are not guaranteed by the supplier. It is also used in ink formulations for printing, leather staining, and paper coloring where consistent red tones are needed without lightfastness requirements.
Buyers commonly source Direct Red 16 for low-cost, high-volume dyeing operations in the textile and packaging industries. It is supplied in 25 kg polypropylene bags, with bulk quantities available in 500 kg drums. The dye requires no fixing agent during application, simplifying processing. Buyers should confirm the exact dye concentration and particle size distribution before ordering, as these affect color yield and dispersion. Lead time and packaging options are subject to supplier confirmation.

Before ordering Direct Red 16 from Aryan Dyes & Pigments, verify the exact CAS number, C.I. designation, and purity level through a sample batch. Confirm that the material matches the described solubility profile and color behavior in sulfuric acid. Request a Certificate of Analysis showing actual test results for moisture, particle size, and active dye content. Do not rely on supplier claims without independent verification.
Logistics are typically handled via sea freight from Mundra or Nhava Sheva ports. Lead time is not stated and must be confirmed directly. Incoterms are likely FOB India, but payment terms such as LC or T/T should be negotiated. Packaging is usually in 25 kg polypropylene bags with inner liners, but drum options may be available. Confirm the container load capacity and palletization method before shipping.
Quality checks should include testing for moisture content via Karl Fischer, particle size distribution by sieve analysis, and color strength via spectrophotometric comparison against a reference standard. Request batch-specific documentation including a material safety data sheet, and confirm compliance with local import regulations for azo dyes. Retain samples from each shipment for future comparison and dispute resolution.
