It is an organic compound used as a pH indicator in acid–base titrations. It is colorless in acidic or neutral media and turns pink to fuchsia in basic conditions within an approximate pH range of 8.2 to 10.0. It is typically presented as a white crystalline solid, slightly soluble in water but soluble in alcohols, where it is commonly available in 0.5% to 1% ready-to-use laboratory solutions. It is an analytical-grade reagent with quality certifications that ensure its purity and reliability in chemical testing.
