Description

1-Bromo-4-n-Heptanoylbenzene is a high-purity aromatic ketone derivative, serving as a versatile and critical building block in advanced organic synthesis. Its molecular structure, featuring both a bromo substituent and a linear heptanoyl chain, makes it an essential intermediate for constructing complex molecules with tailored properties. This compound is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty materials industries for applications in medicinal chemistry and functional material design.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders and metabolic diseases.
• Agrochemical Synthesis: Used in the development of next-generation herbicides and fungicides, where its aromatic core and side chain allow for structural diversification.
• Liquid Crystal & OLED Material Research: Serves as a starting material for synthesizing advanced organic semiconductors and liquid crystal compounds due to its rigid benzene ring and flexible alkyl chain.
• Polymer Chemistry: Acts as a monomer or cross-linking agent in the production of specialty polymers with specific thermal or optical properties.
• Chemical Research & Development: A valuable reagent for method development in cross-coupling reactions (e.g., Suzuki, Heck) and carbonyl chemistry in academic and industrial labs.
• Fine Chemical Production: Intermediate for manufacturing dyes, pigments, and other performance chemicals requiring specific bromo-aryl ketone motifs.

Quality Control

Our 1-Bromo-4-n-Heptanoylbenzene is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting critical parameters such as assay, impurity profile, and physical characteristics. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates, ensuring reliability for your most demanding synthesis workflows.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant packaging. For long-term storage, consider an inert atmosphere to maintain optimal purity.
