4-Dimethylaminobenzaldehyde is an aromatic aldehyde widely used as a key intermediate in organic synthesis, including dye production, pharmaceuticals, and the manufacture of Schiff bases. Known as Ehrlich's reagent, it also serves in analytical laboratories as a colour-forming indicator for detecting indoles and hydrazine. It appears as a yellow to orange crystalline solid with a distinct odor. This chemical has a CAS number of 100-10-7, a molecular formula of (CH3)2NC6H4CHO, and a molecular weight of 149.19 g/mol. It should be stored at ambient conditions and handled with caution, as it carries a warning signal word due to potential health hazards. Molekula supplies 4-Dimethylaminobenzaldehyde from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
