Description

(S)-1-Cyclopentylethanamine Hydrochloride is a high-purity chiral amine salt, a critical building block in advanced organic synthesis. Its value lies in its role as a versatile intermediate for creating enantiomerically pure compounds, which are essential for developing pharmaceuticals with high specificity and reduced side effects. This product is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications in asymmetric synthesis and medicinal chemistry.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and cardiovascular drug candidates.
• Asymmetric Catalysis: Used as a precursor for chiral ligands or auxiliaries in catalytic processes to induce stereoselectivity.
• Agrochemical Research: Serves as a building block for developing novel, enantiomerically pure pesticides and herbicides.
• Fine Chemical Synthesis: Employed in the multi-step synthesis of complex natural products and specialty chemicals requiring specific stereochemistry.
• Academic & R&D: A valuable reagent for methodological development in organic chemistry and medicinal chemistry research programs.

Quality Control

Our (S)-1-Cyclopentylethanamine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high chemical and enantiomeric purity, meeting the stringent requirements for research and development use. Certificates of Analysis (COA) detailing identity, purity (HPLC), chiral purity, and residual solvent levels are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
