Solvent Violet 13 CAS 81-48-1

1. Solvent Violet 13 is an anthraquinone dye primarily used for coloring transparent plastics such as polystyrene (PS), ABS, polycarbonate (PC), PMMA (acrylic), and polyamide resins, where it produces excellent color in molded products .
2. Solvent Violet 13 CAS 81-48-1 is employed in industrial applications for coloring coatings, synthetic fibers (particularly in polyester spun-dyeing), printing inks, and as a photometric reagent for boron determination in analytical chemistry .
3. Solvent Violet 13 is utilized in the cosmetic industry as a colorant (known as D&C Violet No. 2) under regulatory restrictions, with specified limits for impurities including p-toluidine and hydroxyanthracenedione derivatives .
4. Researchers employ Solvent Violet 13 CAS 81-48-1 in dye diffusion studies, polymer compatibility research, and as a certified reference standard for quality control applications, noting its characteristic absorption maxima at 286 nm and 582 nm in toluene .

1. Solvent Violet 13 must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment protected from light, with recommended storage at room temperature in a dark place or at -20°C for long-term stability .
2. Solvent Violet 13 CAS 81-48-1 is classified with GHS hazard statements H317 (May cause allergic skin reaction), H413 (May cause long-lasting harmful effects to aquatic life), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, avoiding formation of dust and aerosols, and using NIOSH-certified dust respirators when necessary .
4. Avoid release to the environment, prevent contact with skin and eyes, wash thoroughly after handling, and follow precautionary statements P261 (avoid breathing dust), P273 (avoid release to environment), and P280 (wear protective gloves/eye protection) .

1. Isolate the spill area, ensure adequate ventilation, and avoid dust formation when Solvent Violet 13 is released; wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator, evacuating non-essential personnel .
2. Collect Solvent Violet 13 CAS 81-48-1 by sweeping or vacuuming without creating dust using non-sparking tools, or absorb with inert materials such as diatomite or universal binders, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure and allergic skin reactions; prevent the product from entering drains or water courses as it is very toxic to aquatic life with long-lasting effects (H413) .
4. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration with flue gas scrubbing .

1. Solvent Violet 13 is combustible with a flash point of approximately 268.7°C, boiling point of 520.7°C at 760 mmHg, and density of 1.373 g/cm³; under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use Solvent Violet 13 CAS 81-48-1 water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; suppress gases/vapors with water spray jet .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Solvent Violet 13 due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray, and contain fire runoff to prevent environmental contamination .
