4-Bromobenzaldehyde CAS 1122-91-4 99%

As a key intermediate, it is used in the synthesis of active molecules containing benzene ring structures, such as antibiotics, antiviral drugs, anti-inflammatory analgesics, and anticancer drugs. For example, it is used to prepare aldol acetals through reactions with amine compounds, or to synthesize biologically active heterocyclic compounds through multi-step reactions.

It is used to construct bromoaryl structures in drug molecules, enhancing drug stability, bioavailability, or targeting.

It is used in the synthesis of insecticides such as bromopropylate; the introduction of bromine atoms enhances the bioactivity of pesticides and improves their insecticidal effect.

It participates in the synthesis of other bromine-containing pesticide molecules, such as fungicides and herbicides.

It is used as a raw material in the production of specific dyes; the presence of bromine atoms can regulate the color, photostability, and dyeing properties of dyes, and is used in the synthesis of high-performance azo dyes, anthraquinone dyes, etc.

In pigment synthesis, it is used to prepare organic pigments with specific optical properties.

It participates in the synthesis of fragrance molecules; by introducing bromine atoms or carrying out further organic reactions, it prepares fragrance compounds with unique aromas and stability.
