TCI C0549 Titan Yellow (CAS 1829-00-1), also known as Thiazole Yellow G, is a direct azo dye supplied for research and experimental use. It is best known as a classical colorimetric reagent for magnesium determination, forming a coloured complex under alkaline conditions that can be measured spectrophotometrically. As a direct dye, it also shows strong affinity for cellulose fibres, making it useful in textile and fibre staining studies. Store the material in a cool, dry place protected from light, and handle the powder with gloves and eye protection to avoid dust exposure and staining.
