Description

7-Nonynoic Acid is a versatile medium-chain alkyne carboxylic acid, serving as a critical building block in advanced organic synthesis. Its terminal alkyne and carboxylic acid functionalities make it a valuable precursor for constructing complex molecular architectures through coupling and derivatization reactions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing new active ingredients and functional materials.

Application

• Pharmaceutical Intermediates: Key synthon for the production of active pharmaceutical ingredients (APIs), particularly in medicinal chemistry for creating novel drug candidates.
• Agrochemical Synthesis: Used in the manufacture of advanced pesticides, herbicides, and plant growth regulators requiring specific alkyne-based side chains.
• Polymer & Material Science: Acts as a monomer or cross-linking agent for producing specialty polymers, coatings, and resins with tailored properties.
• Organic Synthesis & Research: A fundamental reagent for click chemistry (e.g., CuAAC reactions), Sonogashira couplings, and other carbon-carbon bond-forming processes in R&D laboratories.
• Liquid Crystal & Electronic Materials: Serves as a precursor for synthesizing organic semiconductors and liquid crystal compounds used in display technologies.
• Fragrance & Flavor Chemistry: Utilized in the synthesis of specific aroma chemicals and flavoring agents due to its modifiable carbon chain.

Quality Control

Every batch of 7-Nonynoic Acid is produced and tested under a strict quality management system to ensure consistency and reliability for industrial applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. Our standard grade meets high-purity specifications suitable for synthesis, with custom purity levels (e.g., >97%, >99%) available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as a strong acid/organic solvent, ensure the container is compatible and stored separately from bases and oxidizing agents.
