Description

Cyclopentene CAS NO 10016-46-3 is a versatile five-membered cyclic olefin, a key building block in organic synthesis and polymer chemistry. Its reactive double bond and strained ring structure make it an essential intermediate for producing high-value specialty chemicals and advanced materials. This product is primarily sought by R&D laboratories, fine chemical manufacturers, and polymer producers for its unique reactivity profile.

Application

• Organic Synthesis Intermediate: A crucial precursor for synthesizing cyclopentanol, cyclopentanone, and various functionalized cyclopentane derivatives used in pharmaceuticals and agrochemicals.
• Polymer & Copolymer Production: Serves as a monomer for ring-opening metathesis polymerization (ROMP) to create specialty polymers and as a comonomer to modify the properties of polyolefins.
• Pharmaceutical Research: Used in the development of novel drug candidates and active pharmaceutical ingredients (APIs) that incorporate the cyclopentane or cyclopentene scaffold.
• Fragrance & Flavor Industry: Acts as a starting material for the synthesis of aroma chemicals and musk compounds due to its ability to form complex cyclic structures.
• Catalysis & Ligand Synthesis: Employed in the preparation of metallocene catalysts and other organometallic complexes important for asymmetric synthesis and polymerization processes.
• Chemical Research & Development: Utilized in academic and industrial labs for studying reaction mechanisms, developing new synthetic methodologies, and creating novel organic compounds.

Quality Control

Our Cyclopentene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer requirements. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) when not in use to prevent evaporation and degradation. Recommended storage temperature is 2-8°C.
