2,7-Dimethoxy-3-quinolinecarbaldehyde(CAS: 95395-23-6)

2,7-Dimethoxy-3-quinolinecarbaldehyde is a crystalline solid with a molecular weight of approximately 232.22 g/mol. It has a high solubility in organic solvents like ethanol and acetone but is poorly soluble in water. This compound is not highly reactive under normal conditions but can undergo condensation reactions at elevated temperatures. It is stable under acidic and basic conditions but should be stored in a dry environment to prevent hydrolysis.

2,7-Dimethoxy-3-quinolinecarbaldehyde is typically synthesized via the condensation of 2,7-dimethoxyquinoline with acetaldehyde. This reaction is usually catalyzed by a strong acid like hydrochloric acid. The yield is around 75%, and the product is isolated by recrystallization. This method provides a selective route to the target compound with good purity.

2,7-Dimethoxy-3-quinolinecarbaldehyde is used in various industries, including pharmaceuticals, where it serves as a precursor for the synthesis of certain drugs. It is also used in the production of dyes and pigments, as a chromophore in sensors, and in the manufacturing of semiconductors. Its application in polymers is limited due to its chemical reactivity.

When handling 2,7-Dimethoxy-3-quinolinecarbaldehyde, it is important to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. This compound should be handled in a well-ventilated area or a fume hood to prevent inhalation. In case of a spill, it should be cleaned up using appropriate absorbent materials and disposed of according to local regulations.
