CAS 28699-96-9: Indigotetrasulfonatetetrapotassiumsalt

Description:Indigotetrasulfonatetetrapotassiumsalt, commonly known as potassium indigotetrasulfonate, is a synthetic dye and a derivative of indigo. It is characterized by its vibrant blue color, which is attributed to the presence of the indigo structure. This compound is highly soluble in water due to the presence of multiple sulfonate groups, which enhance its ionic nature and facilitate its use in various applications. It is often utilized in textile dyeing, as well as in biological and chemical research as a pH indicator or a staining agent. The presence of four potassium ions in its structure contributes to its stability and solubility. Additionally, this compound is known for its low toxicity, making it suitable for use in various consumer products. Its chemical stability and resistance to fading under light exposure are also notable characteristics, which make it a preferred choice in applications requiring long-lasting color. Overall, potassium indigotetrasulfonate is a versatile compound with significant utility in both industrial and laboratory settings.
