Description

9-Tetradecynoic Acid is a high-purity, long-chain fatty acid derivative featuring a terminal alkyne functional group. This unique molecular structure makes it a valuable chemical building block for advanced organic synthesis and materials science research. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring precise molecular modifications.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of novel active pharmaceutical ingredients (APIs), particularly for creating lipophilic side chains or as a click chemistry component.
• Agrochemical Synthesis: Used in the research and production of specialized herbicides, fungicides, and plant growth regulators where its alkyne moiety enables specific bioactivity.
• Polymer & Material Science: Acts as a monomer or functionalizing agent for creating specialty polymers, surface coatings, and advanced materials with tailored properties.
• Bioconjugation & Probe Development: Employed in biochemical research for labeling biomolecules (proteins, lipids) via copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reactions.
• Organic Synthesis Reagent: Functions as a versatile intermediate in organic chemistry for carbon chain elongation and the synthesis of complex natural products and fine chemicals.
• Lubricant & Surfactant Additive Research: Investigated for developing next-generation additives due to its potential to modify friction and surface interaction properties.

Quality Control

Our 9-Tetradecynoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong oxidizers and bases. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment in a fume hood.
