The vibrant reds that color our world in paints, inks, and plastics often owe their brilliance to a complex interplay of organic chemistry, particularly through the use of azoic coupling components. NINGBO INNO PHARMCHEM CO.,LTD. is a distinguished manufacturer and supplier specializing in these vital chemical intermediates, including Naphthol AS-ITR (CAS 92-72-8). This compound is a cornerstone in the synthesis of Organic Pigment Red C.I. 170, a widely utilized pigment celebrated for its exceptional hue and performance characteristics.

Naphthol AS-ITR, chemically known as 5'-Chloro-3-hydroxy-2',4'-dimethoxy-2-naphthanilide, functions as a critical azoic coupling component. Its molecular structure is precisely engineered to react with diazonium salts, forming the chromophoric azo group that defines the pigment's color. The specific substituents on the naphthanilide ring, such as the chlorine atom and methoxy groups, significantly influence the electron distribution within the molecule, directly impacting the absorption spectrum and thus the resulting red shade of the pigment. For pigment manufacturers, sourcing this intermediate from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures that they can buy with confidence.

The purity of Naphthol AS-ITR is of paramount importance. Impurities can lead to deviations in color shade, reduced tinctorial strength, and diminished lightfastness – all critical parameters for pigment performance. Our manufacturing process at NINGBO INNO PHARMCHEM CO.,LTD. emphasizes achieving a purity of ≥99.0%, guaranteeing that our clients receive a consistent and high-quality product. This dedication to quality makes us a preferred manufacturer and supplier for businesses in China and globally looking to buy reliable chemical intermediates.

Organic Pigment Red C.I. 170, derived from Naphthol AS-ITR, is valued for its application in various demanding sectors. Its bright red shade and excellent fastness properties make it ideal for inks used in packaging and printing, coatings for automotive and industrial applications, and masterbatches for plastics. The ability to buy this key intermediate from a reliable source like us ensures that your production processes remain efficient and your end products meet market expectations. We understand the needs of B2B customers seeking competitive pricing and stable supply.
