Description

5-Decyne is a linear terminal alkyne with the molecular formula C₁₀H₁₈, widely recognized in organic synthesis for its utility as a versatile building block. Its value lies in its ability to participate in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), and other catalytic transformations to create complex molecular architectures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality raw materials for R&D and production.

Application

• Pharmaceutical Intermediates: Serves as a key synthon in the development of active pharmaceutical ingredients (APIs) via click chemistry and cross-coupling reactions.
• Agrochemical Synthesis: Used in the production of specialized herbicides, fungicides, and plant growth regulators that incorporate alkyne functional groups.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the synthesis of specialty polymers, dendrimers, and functionalized surfaces.
• Organic Synthesis & Catalysis: A fundamental reagent in academic and industrial research for constructing carbon-carbon bonds, including Sonogashira and Glaser couplings.
• Liquid Crystal & OLED Materials: Employed in the synthesis of organic semiconductors and liquid crystal compounds due to its rigid linear structure.
• Chemical Probes & Bioconjugation: Utilized for labeling biomolecules (proteins, nucleic acids) in diagnostic assays and bioimaging applications.

Quality Control

Our 5-Decyne is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to verify identity and assay. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with our stringent specifications. We support cGMP and ISO 9001 standards for industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, keep the container tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability to minimize evaporation and degradation. Keep away from strong oxidizing agents.
