Description

Octadecane-1-14C is a high-purity, isotopically labeled standard where the carbon-14 radiolabel is specifically positioned at the first carbon atom of the octadecane chain. This compound is essential for advanced research and development requiring precise metabolic and environmental fate tracking. It is primarily utilized by scientists and quality control laboratories in the pharmaceutical, agrochemical, and environmental science sectors for tracer studies, analytical method development, and as a critical reference material.

Application

• Metabolic Pathway Tracing: Used as a radiolabeled tracer in pharmacokinetic and ADME (Absorption, Distribution, Metabolism, Excretion) studies for drug development.
• Environmental Fate Studies: Tracks the biodegradation, bioaccumulation, and transport of hydrocarbon pollutants in soil and aquatic systems.
• Analytical Reference Standard: Serves as a critical calibrant and internal standard in Gas Chromatography (GC), Liquid Chromatography (LC), and Liquid Scintillation Counting (LSC) for quantitative analysis.
• Biochemical Research: Investigates lipid metabolism, membrane dynamics, and the synthesis of complex biomolecules in biological systems.
• Material Science Research: Used in studies of polymer crystallization, lubricant formulation, and phase behavior of long-chain hydrocarbons.
