Indigo, bearing the CAS number 482-89-3, is a classic dye whose chemical properties make it invaluable across several modern industries. Its distinctive dark blue to violet appearance, derived from its molecular structure C16H10N2O2, has made it a staple, particularly in the textile sector. As a leading manufacturer and supplier of this crucial dye from China, we offer a product that combines historical significance with contemporary industrial demands.

The chemistry of indigo is fascinating. It functions as a vat dye, meaning it requires a reduction process to become soluble before it can bind to fibers, and subsequent oxidation to fix the color. This characteristic is fundamental to its use in dyeing cotton, especially for creating the iconic blue denim that dominates casual wear. The specific way indigo molecules adhere to cotton fibers allows for the characteristic fading that gives denim its unique character over time. For businesses engaged in denim production, securing a consistent supply of high-purity indigo is non-negotiable.

Beyond its primary role in fashion, indigo's applications extend into more specialized fields. It is recognized for its use as a biochemical agent, often employed in laboratory settings for staining or as an indicator. Furthermore, certain purified forms of indigo have found limited use as food colorants, adding to its versatility. The exploration of indigo's properties in fields like organic semiconductors also highlights its potential in advanced material science. For these diverse needs, we act as a reliable indigo dye manufacturer, ensuring purity and availability.
