For professionals in the chemical and manufacturing sectors, a thorough understanding of raw material specifications is critical for successful product development and consistent quality. Solvent Yellow 16 (CAS 4314-14-1) is a prime example of a specialty dye where precise technical details dictate its performance across various applications, from plastics to printing inks. As a leading chemical supplier, we provide an in-depth look at the technical specifications that make Solvent Yellow 16 a preferred choice for many industries.

Chemical Identity and Core Properties

Solvent Yellow 16 is an organic dye characterized by its distinct greenish-yellow color. Its chemical name is typically listed as Solvent Yellow 16, with synonyms such as Sudan Yellow 146 or Transparent Yellow 3G often encountered. The CAS number, 4314-14-1, is its unique identifier in chemical databases. The molecular formula C16H14N4O gives insight into its structure, while its molecular weight of 278.31 g/mol is a standard reference point.

Key physical and chemical properties crucial for formulators include:

  • Appearance: Typically described as a fine yellow powder.
  • Melting Point: Approximately 155°C, which indicates its thermal stability during processing.
  • Assay (Purity): Commonly specified at 99%, ensuring high color strength and minimal impurities.
  • Solubility: As an oil-soluble dye, it demonstrates good solubility in organic solvents like ethanol, acetone, and chloroform, but is insoluble in water. This property is fundamental to its use in non-aqueous systems.
  • Heat Resistance: Good heat resistance, often specified up to 260-280°C in certain polymer applications, allows for its use in higher-temperature processing.
  • Light Fastness: Generally rated as good, typically on a scale where higher numbers indicate better resistance to fading upon light exposure.

These properties make Solvent Yellow 16 an attractive option for manufacturers looking to buy high-quality Solvent Yellow 16.

Applications Driven by Technical Specifications

The precise technical profile of Solvent Yellow 16 directly influences its application suitability:

  • Plastics and Resins: Its heat resistance and solubility allow for excellent dispersion in polymers like PS, HIPS, ABS, PC, and various resins, providing vibrant and stable coloration. R&D scientists often test different grades to optimize melt processing.
  • Paints and Coatings: The dye's clarity and bright shade are valuable for transparent paints and coatings, where its ability to dissolve without leaving residue is paramount.
  • Printing Inks: For ink formulations, its solubility ensures smooth flow and consistent color development, crucial for achieving sharp prints.
  • Aluminum Foil: Used for coloring aluminum foil, its properties contribute to the aesthetic appeal and durability of the colored surface.

For procurement managers, understanding these specifications helps in selecting the appropriate grade and ensures you are sourcing from a reliable Solvent Yellow 16 supplier who can meet your quality demands.
