intermediate for dyes

Reagent Sulfuric Acid 60% is a high-purity acid solution (typically meeting ACS specifications) that offers a practical balance between strong acidity and safe handling. With reduced fuming, lower viscosity, and a lower heat of dilution than 9698% grades, it serves as a versatile stock acid for preparing more dilute solutions, carrying out analytical digestions, and performing moderately strong acid-catalyzed reactions without the extreme aggressiveness of concentrated acid.
