When delving into the world of textile coloration, the choice of dye intermediates significantly impacts the final product's quality, vibrancy, and performance. Among the most crucial of these is Metanilic Acid, identified by its CAS number 121-47-1. This organic compound serves as a foundational element in the synthesis of a wide array of dyes, making it an indispensable raw material for manufacturers worldwide. As a leading supplier of Metanilic Acid in China, we understand the critical needs of our B2B clients—research scientists, formulators, and purchasing managers seeking high-quality, consistent, and cost-effective chemical solutions.

Metanilic Acid, also known by its chemical name 3-Aminobenzenesulfonic acid, is typically supplied as a pinkish-white powder. Its molecular structure (C6H7NO3S) and properties make it an exceptionally versatile intermediate. Its primary utility lies in the production of various dye classes, including:

  • Acid Dyes: These dyes are commonly used for coloring protein fibers like wool and silk, as well as polyamide fibers. Metanilic Acid plays a key role in achieving the desired shade and fastness properties.
  • Reactive Dyes: Essential for dyeing cotton and other cellulosic fibers, reactive dyes form a covalent bond with the fiber, leading to excellent wash fastness. Metanilic Acid is a key building block in many reactive dye formulations.
  • Azo Dyes: This vast class of dyes, characterized by the azo group (-N=N-), is produced using Metanilic Acid in combination with other aromatic compounds. They are widely used across industries for their broad color spectrum and cost-effectiveness.
  • Sulfur Dyes: Metanilic Acid is also employed in the creation of sulfur dyes, known for their deep shades and good fastness properties, particularly on cotton.
