CAS 120-14-9: 3,4-Dimethoxybenzaldehyde

Description:3,4-Dimethoxybenzaldehyde, with the CAS number 120-14-9, is an organic compound belonging to the class of aromatic aldehydes. It features a benzene ring substituted with two methoxy groups (-OCH3) at the 3 and 4 positions, along with an aldehyde functional group (-CHO) at the first position. This compound is typically a colorless to pale yellow liquid with a sweet, floral aroma, making it useful in the fragrance industry. It has a moderate boiling point and is soluble in organic solvents such as ethanol and ether, but has limited solubility in water due to its hydrophobic methoxy groups. 3,4-Dimethoxybenzaldehyde is often employed as an intermediate in organic synthesis, particularly in the production of various pharmaceuticals and agrochemicals. Its reactivity is characterized by the presence of the aldehyde group, which can undergo typical reactions such as oxidation and condensation. Safety precautions should be taken when handling this compound, as it may cause irritation to the skin and eyes.
