Description

2-Propynoyl Chloride,3-Phenyl- is a specialized organic acid chloride derivative, serving as a high-value building block in advanced chemical synthesis. Its core value proposition lies in its highly reactive propynoyl chloride group, which enables efficient acylation and coupling reactions under controlled conditions. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical sectors, where it is used to introduce the 3-phenylpropynoyl moiety into target molecules, creating novel compounds with specific biological activities.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting central nervous system (CNS) disorders and inflammatory pathways.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators that require the phenylpropynoyl functional group.
• Material Science Research: Employed as a monomer or cross-linking agent in the development of specialty polymers and advanced organic materials.
• Chemical Biology & Proteomics: Acts as a reactive probe for labeling and modifying proteins, enzymes, and other biomolecules in research applications.
• Fine Chemical Production: Serves as a precursor for synthesizing complex fragrance compounds, dyes, and other high-value specialty chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, it must be kept away from moisture, heat, and incompatible materials such as bases, alcohols, and amines. Use appropriate corrosion-resistant storage equipment. Keep container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation.
