Description

Octadecanol-1-14C is a carbon-14 labeled isotopologue of stearyl alcohol, a long-chain primary fatty alcohol. This radiolabeled compound is essential for precise metabolic and pharmacokinetic studies, enabling researchers to track the fate of stearyl alcohol derivatives in complex biological and chemical systems. It is a critical tool for scientists in pharmaceutical R&D, agrochemical development, and advanced material science who require definitive data on absorption, distribution, metabolism, and excretion (ADME) pathways.

Application

• Tracer Studies in Metabolism Research: Used as a radiolabeled tracer to investigate the metabolic pathways and biotransformation of stearyl alcohol and its derivatives in vivo and in vitro.
• Pharmaceutical Development: Critical for ADME (Absorption, Distribution, Metabolism, Excretion) studies of drug candidates containing long-chain alkyl groups or formulated with stearyl alcohol.
• Agrochemical Research: Employed to study the environmental fate, degradation, and uptake of surfactants, emulsifiers, or active ingredients in pesticide and herbicide formulations.
• Material Science & Polymer Chemistry: Serves as a labeled precursor or additive to study the incorporation, distribution, and stability of stearyl alcohol in polymers, coatings, and lubricants.
• Biochemical Pathway Analysis: Facilitates the elucidation of lipid synthesis, modification, and catabolism pathways in biological systems.
• Quality Control & Method Development: Used as an internal standard in advanced analytical techniques like LC-MS for the quantification of stearyl alcohol in complex matrices.
