Description

3-Ethynylcyclopentylmethanol is a specialized organic building block featuring both a terminal alkyne and a primary alcohol functional group on a cyclopentane ring. This unique bifunctional structure makes it a valuable intermediate for synthesizing complex molecules in pharmaceutical and advanced material research. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing novel molecular architectures.

Application

• Pharmaceutical Intermediate: A key synthon for the construction of active pharmaceutical ingredients (APIs), particularly in the development of novel small-molecule therapeutics.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, leveraging its reactive alkyne group for coupling reactions.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands used in asymmetric catalysis and transition metal complexes.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the synthesis of specialty polymers, dendrimers, and advanced materials with tailored properties.
• Chemical Biology Probes: Utilized in click chemistry (CuAAC) applications to attach fluorescent tags or other reporter molecules to biomolecules for imaging and diagnostic purposes.
• Academic & Industrial R&D: A versatile building block for exploratory organic synthesis and methodology development in research laboratories.

Quality Control

Our 3-Ethynylcyclopentylmethanol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity, assay, and impurity profiles. We support cGMP and ISO standards for research and development applications.

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). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
