Description

1,2-Cyclopentanediamine CAS NO 41330-23-8 is a versatile chiral diamine building block essential for the synthesis of complex organic molecules. Its rigid cyclopentane backbone and two adjacent amino functional groups make it a valuable precursor for creating ligands, catalysts, and active pharmaceutical ingredients (APIs). This high-purity intermediate is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing new compounds with targeted biological activity.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs).
• Catalyst & Ligand Synthesis: Used to create sophisticated chiral ligands and organocatalysts for asymmetric synthesis.
• Agrochemical Research: Serves as a precursor in the development of new herbicides, fungicides, and plant growth regulators.
• Polymer Modification: Employed in the production of specialty polyamides, epoxy curing agents, and other performance polymers.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D in organic and medicinal chemistry.
• Chelating Agent Precursor: Used to synthesize chelating compounds for metal ion sequestration and catalysis.

Quality Control

Our 1,2-Cyclopentanediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage or after opening to prevent degradation.
