Nitrazine yellow

Description:

Nitrazine yellow, with the CAS number 5423-07-4, is a synthetic dye primarily used as a pH indicator. It exhibits a distinct yellow color in acidic conditions and transitions to a blue hue as the pH increases, making it useful for various applications in laboratories and industries. This compound is soluble in water and exhibits stability under normal conditions, although it may degrade when exposed to strong light or extreme pH levels. Nitrazine yellow is often utilized in microbiological assays and as a reagent in chemical analyses due to its clear colorimetric changes. Additionally, it has applications in the textile industry for dyeing purposes. Safety considerations include potential irritant effects on skin and eyes, necessitating appropriate handling precautions. Overall, Nitrazine yellow serves as a valuable tool in both analytical chemistry and industrial processes, providing a visual means to assess pH levels effectively.
