Description

6-Heptynoic Acid is a versatile alkyne-containing carboxylic acid building block of significant interest in advanced organic synthesis. Its terminal alkyne and carboxylic acid functionalities make it a valuable precursor for constructing complex molecular architectures via coupling and cyclization reactions. This compound is primarily utilized by researchers and process chemists in the pharmaceutical, agrochemical, and material science industries for developing new active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in creating alkyne-tagged molecules for bioconjugation or as a core scaffold.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators that require specific alkyne motifs.
• Material Science: Serves as a monomer or cross-linking agent in the production of specialty polymers, resins, and advanced materials with tailored properties.
• Chemical Biology & Proteomics: Acts as a click chemistry reagent (via CuAAC or SPAAC reactions) for labeling biomolecules, enabling activity-based protein profiling and diagnostic assay development.
• Organic Synthesis: A fundamental synthon for Sonogashira coupling, Huisgen cycloaddition, and other metal-catalyzed transformations to create complex organic molecules.
• Liquid Crystal & OLED Research: Employed in the synthesis of organic semiconductors and liquid crystal materials due to its rigid linear structure and functional handles.

Quality Control

Our 6-Heptynoic Acid is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to verify identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for pharmaceutical and industrial applications.

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 strong bases, oxidizing agents, and sources of ignition. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment in a fume hood.
