Understanding the chemical profile of a compound is fundamental for its effective industrial application. Solvent Violet 13, with CAS number 81-48-1, is a prime example of an anthraquinone dye that offers a unique set of properties beneficial for various manufacturing sectors. As a prominent manufacturer and supplier in China, we aim to provide clarity on this versatile colorant.

The chemical name for Solvent Violet 13 is 1-hydroxy-4-(4-methylanilino)anthracene-9,10-dione. Its molecular formula is C21H15NO3, and it has a molecular weight of approximately 329.35 g/mol. This organic compound presents as a violet to brown powder, readily soluble in non-polar solvents such as xylene, which is a key characteristic for its designation as a 'solvent' dye.

Its solubility profile makes Solvent Violet 13 highly compatible with a wide range of matrices. In the plastics industry, it is extensively used for coloring materials like Polystyrene (PS), Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Poly(methyl methacrylate) (PMMA), Polyethylene Terephthalate (PET), and Polyvinyl Chloride (PVC). The dye imparts a vibrant violet color with excellent uniformity, crucial for applications like masterbatches or direct coloring during polymer processing.

Beyond plastics, Solvent Violet 13 finds application in coloring oils, fats, waxes, greases, and solvent-based inks and adhesives. Its stability under various conditions is a significant asset. The dye exhibits good heat resistance, often usable at temperatures up to 300°C in specific polymer systems, ensuring color integrity during high-temperature manufacturing processes. Furthermore, its lightfastness, generally rated between 6-8, contributes to the longevity of the coloration, preventing premature fading.
