Description

n-Valeroyl Bromide is a versatile and highly reactive acyl bromide derivative, essential for introducing the valeryl moiety in organic synthesis. Its primary value lies in its role as a key building block for the production of pharmaceuticals, agrochemicals, and advanced materials, where precise molecular construction is critical. This compound is particularly sought after by research and development chemists, process engineers, and manufacturers in the fine chemical, pharmaceutical, and specialty chemical industries.

Application

• Pharmaceutical Intermediates: A key reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly for constructing amide bonds and ester linkages.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that require the valeric acid backbone.
• Polymer Chemistry: Serves as a monomer or modifying agent in the creation of specialty polymers and functional materials.
• Organic Synthesis Reagent: Employed in Friedel-Crafts acylation, nucleophilic substitution, and other reactions to introduce acyl groups.
• Liquid Crystal & OLED Material Precursor: Acts as a starting material for synthesizing advanced electronic and display components.
• Flavor & Fragrance Industry: Used in the controlled synthesis of specific esters that contribute to complex flavor and aroma profiles.
• Peptide Chemistry: Can be utilized for the temporary protection of amino groups or as a coupling agent in specific peptide synthesis strategies.
• Chemical Research: A valuable tool in academic and industrial R&D for exploring new synthetic methodologies and compound libraries.

Quality Control

Our n-Valeroyl Bromide is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified for the specific grade. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizers.
