Description

1-Pentene is a fundamental linear α-olefin with the CAS registry number 25377-72-4, serving as a critical building block in industrial organic synthesis. Its high reactivity and defined carbon chain make it an essential monomer and chemical intermediate for producing a wide range of polymers and specialty chemicals. This product is primarily needed by manufacturers in the polymer, petrochemical, and fine chemical sectors for applications such as copolymerization, alkylation, and the synthesis of flavors and fragrances.

Application

• As a comonomer in the production of linear low-density polyethylene (LLDPE) to modify density and mechanical properties.
• As a key intermediate in the synthesis of amyl alcohols, amyl mercaptans, and other C5 derivatives for various industrial uses.
• In the manufacture of synthetic lubricants and lubricant additives to enhance performance characteristics.
• As a starting material for alkylation processes in the petrochemical industry.
• For the production of flavor and fragrance ingredients through controlled oxidation or other functionalization reactions.
• In research and development as a standard or reagent in catalytic studies and organic synthesis.

Quality Control

Our 1-Pentene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including gas chromatography (GC), to verify identity, assay, and impurity profiles. Certificates of Analysis (COA) documenting all critical specifications are available for every batch and provided upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is between 2°C and 25°C. Keep container tightly sealed when not in use to prevent evaporation and maintain product integrity.
