Solvent Yellow 114

1. Basic Information

· Product Name: Solvent Yellow 114

· Synonyms: C.I. Solvent Yellow 114; Fluorescent Yellow 114

· Chemical Class: Coumarin-based Fluorescent Dye

· C.I. Number: C.I. 47020

· CAS No.: 38711-86-7

· Molecular Formula: C₂₄H₂₃NO₃ (Typical for common derivatives)

2. Physical & Chemical Properties

· Appearance: Bright yellow to greenish-yellow fine powder or crystalline powder.

· Fluorescence: Exhibits intense bright yellow-green fluorescence under ultraviolet (UV-A, 365 nm) light. This is its defining characteristic.

· Solubility: Highly soluble in common organic solvents such as toluene, xylene, esters, ketones, and chlorinated hydrocarbons. Insoluble in water.

· Melting Point: Approximately 185 - 190 °C.

· Stability: Shows good thermal stability for common processing applications. It possesses moderate lightfastness, but prolonged exposure to strong UV/sunlight may cause fading. Chemical stability to acids and alkalis is moderate.

3. Key Features & Primary Applications

This dye is valued for its high fluorescence quantum yield, brilliant shade, and good compatibility with hydrophobic matrices.

· Plastics Coloring: The major application is for mass coloration of engineering plastics, including:

· Polystyrene (PS)

· Polymethyl Methacrylate (PMMA/Acrylic)

· Polycarbonate (PC)

· ABS resins

· Typical End-Use Products: Toys, decorative items, advertising signs, safety markers, knobs, and optical filters.

· Coatings & Inks: Used in the formulation of fluorescent solvent-based paints, screen printing inks, and security inks.

· Fuel & Oil Marking: Employed as a dye and tracer for gasoline, lubricants, and specialty fuels.

· Research & Specialty Uses: Can serve as a fluorescent tracer or probe in laboratory settings.

4. Handling & Safety

· Safety Precautions: Avoid inhalation of dust and direct contact with skin or eyes. Use with adequate ventilation. Personal protective equipment (PPE) such as gloves and dust masks is recommended.

· Regulatory Status: Compliance status (e.g., REACH, FDA for indirect food contact) depends on the specific application and region. It is crucial to consult the current Material Safety Data Sheet (MSDS/SDS) and relevant regulatory lists for the intended use.

· Storage: Store in a tightly closed container in a cool, dry, well-ventilated place away from direct sunlight and ignition sources.

5. Key Selling Points

· Brilliant Fluorescence: Offers very bright yellow-green emission.

· Good Solubility & Dispersibility: Easy to incorporate into solvent-based systems and many molten polymers.

· Commercial Availability: Widely produced and available from major dye manufacturers.

Sample Concise Summary (for quick reference):

Solvent Yellow 114 (CAS 38711-86-7) is a high-performance coumarin fluorescent dye.
