For professionals in the dye manufacturing industry, a profound understanding of chemical compounds is indispensable. Among the most iconic and widely used is C16H10N2O2, commonly known as Vat Dye Indigo Blue 1S. This compound forms the backbone of countless blue textile applications, particularly in denim. NINGBO INNO PHARMCHEM CO.,LTD. as a distinguished C16h10n2o2 dye manufacturer, provides an in-depth look into the chemical characteristics and production considerations of this essential colorant.


Vat Dye Indigo Blue 1S is distinguished by its unique molecular structure, which dictates its dyeing mechanism. It is characterized by its insolubility in water and alcohol in its oxidized state, a property that necessitates a reduction process within a 'vat' to render it soluble (leuco-indigo) for fiber absorption. Upon exposure to air, the leuco-indigo oxidizes back to its insoluble blue form, chemically bonding with the textile fibers. This process is key to the dye's renowned fastness and durability, making it an ideal high purity indigo dye powder for textiles.


Our commitment as a Vat Dye Indigo Blue 1S supplier is reflected in the stringent quality control measures applied during manufacturing. We ensure a minimum content of ≥93.0% and exceptionally low moisture levels (≤1.0%), which are critical for predictable performance in large-scale dye formulations. These specifications contribute to a stable pH range of 9.5-10.5 in solution, ensuring optimal conditions for dye reduction and uptake. Understanding these precise chemical parameters allows dye manufacturers to formulate their products with confidence, knowing they are working with a reliable and consistent raw material.


The role of C16H10N2O2 extends beyond mere coloration; its granular form and dark blue powder appearance are carefully controlled to facilitate ease of handling and dispersion in industrial settings. As an integral component for industrial fabric dyeing solutions, its properties are fine-tuned to support efficient and high-yield production cycles. Partnering with a specialized C16h10n2o2 dye manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures access to a product that is not only chemically sound but also optimized for the practical demands of modern dye synthesis and application.
