Catechol Violet (Pyrocatechol Violet) is a synthetic organic dye and pH indicator, widely used in analytical chemistry for titrations, complexometric assays, and as a visual indicator in acid-base reactions due to its distinct color changes. It appears as a dark green to black powder, soluble in water and alcohol; it is red in strongly acidic solution, turns yellow above about pH 1.5–2, and changes from yellow to violet near neutral pH (about pH 6–7). CAS 115-41-3, molecular formula C19H14O7S with a molecular weight of 386.38 g/mol. Stable at ambient conditions with no signal word required. Molekula supplies Catechol Violet from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
