4-(Methylsulfonyl)benzaldehyde(CAS: 5398-77-6)

4-(Methylsulfonyl)benzaldehyde (CAS: 5398-77-6) is an organic compound with the chemical formula C8H8O2S. It features a benzene ring substituted with a methylsulfonyl group at the 4-position and an aldehyde functional group. This compound is a white crystalline solid, soluble in organic solvents, and exhibits moderate polarity. It is commonly used as an intermediate in chemical synthesis due to its reactivity and structural versatility.

4-(Methylsulfonyl)benzaldehyde (CAS: 5398-77-6) is primarily used in pharmaceuticals as a building block for drug development, particularly in compounds targeting inflammation and oxidative stress. It also serves in the fragrance and flavor industry as a component in synthetic aroma compounds. Additionally, it is employed in industrial applications for polymer synthesis and research in organic chemistry for creating sulfur-containing derivatives.

4-(Methylsulfonyl)benzaldehyde (CAS: 5398-77-6) is generally considered safe when handled properly, but it may pose moderate toxicity risks upon inhalation or skin contact. Safety data sheets (SDS) recommend using appropriate personal protective equipment (PPE), such as gloves and goggles, and working in a well-ventilated area. It is not classified as carcinogenic, but adherence to standard chemical safety protocols is essential to minimize exposure and health risks.

4-(Methylsulfonyl)benzaldehyde (CAS: 5398-77-6) should be stored in a cool, dry place (ideally below 25°C), away from light and moisture. It requires a sealed container made of glass or HDPE to prevent degradation. While stable under normal conditions, it should be kept in a ventilated storage area to avoid potential fumes. Proper labeling and storage away from incompatible substances are also recommended.
