ALUMINON Uses

Aluminon (CAS NO.569-58-4),the triammonium salt of aurin tricarboxylic acid, is a dye commonly used to detect the presence of the aluminium ion in an aqueous solution. In addition to its use in qualitative inorganic analysis, aluminon has applications in pharyngeal aerosols. It forms brilliantly colored lake pigments with aluminum, chromium, iron, and beryllium.

ALUMINON Production

Aluminon is prepared by reacting sodium nitrite with salicylic acid, adding formaldehyde, then treating with ammonia.
