Acid Red 52 from Sparrowings International, based in Gujarat, India, is a synthetic acid dye with the CAS number 3520-42-1 and EINECS number 222-529-8. Known also as Acid Rhodamine, it features the molecular formula C27H29N2NaO7S2 and is supplied in powder form for industrial applications. This dye is particularly valued in textile, leather, plastic, and food dyestuff sectors for its ability to produce intense red shades with strong colorfastness properties.
The dye’s chemical composition includes sulfonate groups that ensure high water solubility, a critical factor for even dispersion in dye baths. Standard industry tests for such dyes include assessing dye strength (typically 100% ± 3%), moisture content (maximum 5%), and insoluble matter (maximum 1%). Sparrowings International’s product meets typical specifications for acid dyes, including stability in acidic to neutral pH ranges and compatibility with a wide array of natural and synthetic fibers.
Textile manufacturers often use Acid Red 52 for dyeing wool, silk, and nylon due to its excellent penetration and fixation on protein-based fibers. In leather applications, it provides uniform coloring with good resistance to crocking and migration. The dye is also employed in plastics and coatings where vibrant, lightfast red hues are required. Buyers should specify their intended application to ensure the supplier provides the appropriate grade and auxiliary recommendations.
