Description

4-(4-Bromophenyl)Butanoyl Chloride is a versatile and reactive organic intermediate characterized by its brominated aromatic ring and acid chloride functionality. This compound is critical for the synthesis of more complex molecules, enabling the introduction of the 4-(4-bromophenyl)butanoyl moiety into target structures. It is primarily sought after by research chemists and process development scientists in the pharmaceutical and agrochemical industries for applications in drug discovery and the production of fine chemicals.

Application

• Key intermediate in the synthesis of pharmaceutical active ingredients (APIs), particularly for compounds targeting central nervous system disorders.
• Building block for the development of novel agrochemicals, including herbicides and fungicides.
• Precursor in material science for the creation of specialty polymers and liquid crystals.
• Used in organic research for coupling reactions, such as Friedel-Crafts acylation and amide bond formation.
• Starting material for the production of dyes and pigments with specific light-absorption properties.
• Intermediate in the synthesis of ligands for catalytic systems and metal-organic frameworks (MOFs).

Quality Control

Our 4-(4-Bromophenyl)Butanoyl Chloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under an inert atmosphere such as nitrogen or argon to prevent degradation. Keep away from heat, open flames, and incompatible materials.
