    Tolualdehyde (unknown isomer) CAS 1334-78-7 is primarily used as a reactive intermediate in aromatic synthesis. In fragrance and flavor applications it functions as an aroma compound and building block for more complex scent and flavor ingredients; in cosmetics and personal care it is handled as a fragrance-related intermediate; in industrial manufacturing it is used to synthesize other aryl aldehydes and related chemicals, contributing to the production of dyes, pigments, and specialty intermediates; in coatings and inks it can act as a precursor to resins or as a formulation component; in pharmaceutical R&D it is evaluated as a building block for aromatic compounds and heterocycles. All uses are subject to local regulations and formulation limits.
