Acid Red 4 is a synthetic organic dye with CAS number 5858-39-9, supplied by Krishna Impex from their facility in Bhayander, Maharashtra. It delivers a vibrant red hue with strong color retention under wash and light exposure, making it a reliable choice for industrial dyeing processes. The product is water-soluble and designed for uniform dispersion in aqueous solutions, ensuring consistent application across textile, plastic, and coating substrates.

The dye’s molecular structure provides high affinity for protein and polyamide fibers, which is typical for acid dyes in this class. Its standard application pH range is 2.5 to 4.5, where it achieves optimal fixation and color yield. Industry practice for Acid Red 4 includes typical moisture content below 5%, a standard purity of 85% to 95% by HPLC, and a maximum insoluble matter of 0.5% to ensure minimal residue in final products.

Textile manufacturers use Acid Red 4 for dyeing wool, silk, and nylon, while plastic producers incorporate it into polymers for colored end products. Buyers sourcing bulk quantities should confirm minimum order quantities and packaging formats directly with Krishna Impex, as these terms are not specified in the listing. The dye’s compatibility with standard dyeing machinery and resistance to common processing chemicals make it a practical option for large-scale operations.

Krishna Impex operates from B-10, Om Sai Industrial Estate, located on Bhayander East Phatak Road in Thane, Maharashtra.
