Product Description:

4,6-Dimethoxysalicylaldehyde is an organic compound featuring a salicylaldehyde core substituted with two methoxy groups at the 4 and 6 positions. It is a pale yellow to off-white crystalline powder with a molecular formula of C9H10O4. This compound is a key intermediate in the synthesis of various functional organic materials. Its primary application is in the preparation of fluorescent dyes, particularly coumarin derivatives, which are widely used as laser dyes, fluorescent probes, and optical brightening agents. The aldehyde and phenolic hydroxyl groups provide reactive sites for constructing complex heterocyclic systems with desired photophysical properties. It also serves as a versatile building block in organic synthesis for constructing ligands and other fine chemicals. Handling requires standard precautions for laboratory chemicals. It should be stored in a cool, dry place away from strong oxidizing agents.
