pinacryptol yellow

Description:
Pinacryptol yellow, with the CAS number 25910-85-4, is a synthetic organic compound primarily used as a dye and pH indicator. It belongs to the class of azo dyes, characterized by the presence of one or more azo groups (-N=N-). This compound exhibits a vibrant yellow color, making it suitable for various applications in textiles, food, and biological staining. Pinacryptol yellow is known for its solubility in water, which allows it to be easily incorporated into aqueous solutions. Its stability under light and heat conditions is relatively good, although it may degrade under extreme conditions. The dye's pH sensitivity enables it to change color in response to varying acidity or alkalinity, which is useful in analytical chemistry and biological assays. However, like many synthetic dyes, it may pose environmental and health concerns, necessitating careful handling and disposal. Overall, pinacryptol yellow is a versatile compound with significant utility in both industrial and laboratory settings.
