Description

7-Pentacosene is a high-purity, long-chain terminal alkene with significant utility in advanced material synthesis and chemical research. Its well-defined linear structure makes it a valuable intermediate for creating specialty polymers, surfactants, and fine chemicals. This compound is particularly sought after by R&D laboratories and industrial chemists in the sectors of olefin metathesis, lubricant formulation, and organic synthesis where precise molecular architecture is critical.

Application

• Olefin Metathesis Catalyst Research: Serves as a key substrate for developing and testing novel homogeneous and heterogeneous metathesis catalysts.
• Specialty Polymer Synthesis: Used as a co-monomer or chain-transfer agent in the production of linear low-density polyethylene (LLDPE) and other polyolefins with tailored properties.
• Lubricant & Fuel Additive Intermediate: Acts as a precursor for synthesizing high-performance viscosity modifiers and friction reducers.
• Organic Synthesis Building Block: Employed in hydroformylation, polymerization, and other catalytic reactions to construct complex organic molecules.
• Surface Science & Material Coatings: Utilized in the study of self-assembled monolayers (SAMs) and for creating hydrophobic surface coatings.
• Chemical Standard & Reference Material: Provides a pure standard for analytical calibration in gas chromatography (GC) and mass spectrometry (MS).
• Flavor & Fragrance Industry: May serve as an intermediate for the synthesis of specific long-chain aroma chemicals.

Quality Control

Every batch of our 7-Pentacosene is manufactured and tested under a strict quality management system. We guarantee high purity and batch-to-batch consistency through rigorous analytical protocols including GC, GC-MS, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to ensure it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This product is easily oxidized; minimize headspace in opened containers and reseal immediately after use.
