Description

3-Butynenitrile is a highly versatile, low molecular weight alkyne nitrile building block, essential for advanced organic synthesis. Its terminal alkyne and nitrile functionalities make it a critical precursor for constructing complex molecular architectures via click chemistry, cross-coupling, and cycloaddition reactions. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for creating active ingredients, ligands, and novel polymers.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the synthesis of heterocyclic compounds, enzyme inhibitors, and novel drug candidates.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators requiring alkyne motifs.
• Polymer & Material Science: Acts as a monomer or cross-linking agent for creating specialty polymers, conductive materials, and high-performance resins.
• Ligand & Catalyst Development: Employed in the preparation of sophisticated ligands for transition metal catalysis and organometallic complexes.
• Click Chemistry Reagent: A fundamental building block for Huisgen 1,3-dipolar cycloaddition reactions to create triazole linkages.
• Chemical Research: Utilized in academic and industrial R&D for exploring new reaction pathways and synthesizing complex natural product analogs.

Quality Control

Our 3-Butynenitrile is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including GC, IR, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for our production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile nature, keep away from heat, sparks, and open flames. Containers should be kept upright and securely sealed when not in use.
