Description

Cyclopentyl Isothiocyanate is a versatile organosulfur compound characterized by its reactive isothiocyanate functional group. This high-purity intermediate is critical for synthesizing advanced molecules in pharmaceutical and agrochemical research, offering a reliable building block for introducing the cyclopentyl moiety. It is primarily sought after by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and crop protection industries for constructing novel active ingredients and complex heterocycles.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel drug candidates, particularly in kinase inhibitor and CNS-active compound research.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, leveraging its bioisosteric properties.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands in asymmetric catalysis and metal-organic frameworks (MOFs).
• Polymer Modification: Employed to introduce functional groups into polymer backbones to alter material properties like adhesion and thermal stability.
• Chemical Biology Probes: Utilized in the synthesis of activity-based probes (ABPs) for studying enzyme function and target engagement.
• Flavor and Fragrance Chemistry: Acts as a building block for synthesizing specific sulfur-containing aroma compounds.

Quality Control

Our Cyclopentyl Isothiocyanate is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all critical specifications are provided with each shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C or as specified on the label. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation.
