      Product Detail  


    2-Methyl-4-nitroaniline (CAS: 99-52-5), also known as 4-Nitro-o-toluidine or Fast Red RL Base, is a high-purity organic intermediate widely used in the dye, pharmaceutical, and materials industries .

    Chemical & Physical Properties
    This compound has the molecular formula C₇H₈N₂O₂ and a molecular weight of 152.15 g/mol . It appears as a yellow to dark yellow crystalline solid with a melting point range of 130–133 °C .

    Key Applications

    • Dye Manufacturing: As a critical azo dye intermediate (Red Base RL), it provides vibrant yellow to orange-red colors for textiles and pigments with excellent lightfastness .

    • Pharmaceutical Development: It serves as a building block for synthesizing anti-inflammatory and analgesic drug candidates .

    • Specialty Materials: Due to its "push-pull" electronic structure, it is utilized in nonlinear optical materials and polymer formulations to enhance thermal and mechanical properties .

    Specifications & Handling
    Commercial grades offer ≥98% purity (HPLC/GC) . Standard packaging is 25 kg fiber drums, with storage recommended at 0–8 °C . Note that this product is classified as a toxic substance (UN 2660, Class 6.1) and should be handled with appropriate protective equipment .

    Items Specifications
    Key Azo Dye Intermediate (Red Base RL) This compound is widely utilized as a crucial intermediate in the manufacturing of azo dyes, particularly known as Red Base RL or Fast Red RL Base . It serves as a diazo component, providing vibrant yellow to orange-red colors for dyeing and printing textile fibers such as cotton, linen, and also for producing paints and pigments . Its excellent lightfastness and stability make it highly desirable for these applications .
    Push-Pull System for Advanced Optical Materials The molecular structure of 2-methyl-4-nitroaniline features a unique "push-pull" system created by the electron-donating methyl (-CH₃) and amino (-NH₂) groups paired with the electron-withdrawing nitro group (-NO₂) . This arrangement allows for efficient intramolecular charge transfer, giving the compound significant nonlinear optical (NLO) properties . Research has shown that its derivatives exhibit high second harmonic generation (SHG) efficiency and electro-optical capabilities, making it valuable for developing photonic devices, laser frequency conversion, and high-speed display technologies .
    Versatile Building Block for Pharmaceuticals & Polymers Beyond dyes, this compound serves as a versatile synthetic building block in pharmaceutical research and polymer chemistry . It is a precursor for synthesizing molecules with potential anti-inflammatory and analgesic properties . In material science, it is used to formulate specialty polymers, enhancing thermal stability and mechanical properties for automotive and aerospace applications, and can be incorporated into electrospun nanofibers to improve piezoelectric properties for sensors and energy harvesting devices .
