Description

4-Bromobutyronitrile is a versatile brominated nitrile compound that serves as a crucial synthetic intermediate in organic chemistry. Its value lies in its bifunctional reactivity, featuring both a reactive bromine atom and a nitrile group, enabling its use in carbon chain elongation and heterocycle formation. This high-purity building block is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of various drug candidates, including potential CNS-active compounds and enzyme inhibitors.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators requiring specific bromoalkyl chains.
• Heterocyclic Chemistry: A precursor for the construction of nitrogen-containing heterocycles like pyrrolidines and piperidines via cyclization reactions.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the development of specialty polymers, resins, and functional materials.
• Organic Synthesis Reagent: Employed in nucleophilic substitution reactions and as a starting material for converting the nitrile to other functional groups (e.g., acids, amides).
• Liquid Crystal & Electronic Chemical Intermediate: Used in the synthesis of advanced organic molecules for electronic applications.

Quality Control

Our 4-Bromobutyronitrile is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee batch-to-batch consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong bases and reducing agents. Recommended storage temperature is 2-8°C for long-term stability. Keep container tightly sealed when not in use to prevent moisture absorption.
