Acid Blue 90, widely recognized as Brilliant Blue G250 (CAS 6104-58-1), is a synthetic organic dye of considerable industrial significance. Its specific chemical properties dictate its performance and suitability across various applications, particularly in textile and leather dyeing. NINGBO INNO PHARMCHEM CO.,LTD., a prominent China-based manufacturer and supplier, offers a detailed look at the characteristics that make this dye a preferred choice for many industrial processes.

Chemically, Acid Blue 90 is characterized by its molecular formula C47H48N3NaO7S2 and a molecular weight of 854.02. Its physical appearance is typically a dark brown powder. However, upon dissolution, it yields a vibrant and bright blue color. This transformation is a key attribute for its use in dyeing. Its solubility profile is also noteworthy: it is slightly soluble in cold water but readily soluble in hot water and ethanol, which facilitates its application in aqueous-based dyeing systems and printing pastes. When dissolved in concentrated sulfuric acid, it exhibits a blood-red color, turning orange-red upon dilution, and its aqueous solution turns purple when treated with sodium hydroxide solution, indicating its chemical reactivity and pH sensitivity.

The industrial significance of Acid Blue 90 lies in its versatility and consistent performance. As an acid dye, it is primarily used for dyeing protein fibers like wool and silk, as well as polyamide fibers such as nylon. Its ability to produce a brilliant blue shade with good fastness properties (particularly after appropriate after-treatments) makes it valuable in the fashion and textile industries. Its use in leather dyeing further broadens its industrial application scope.

For procurement managers and industrial users, understanding these chemical properties is crucial when integrating Acid Blue 90 into their formulations. The dye's stability under specific pH conditions and its solubility characteristics directly impact the efficiency and outcome of dyeing processes.
