Description

Docosanoic-12,12,13,13-D4 Acid is a high-purity, isotopically labeled derivative of behenic acid, where four hydrogen atoms at the 12 and 13 positions are replaced with deuterium (D). This stable isotope labeling is critical for applications requiring precise analytical tracking and metabolic studies. It serves as an essential internal standard and tracer in advanced research and development within the pharmaceutical, biochemical, and material science sectors.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of behenic acid and related long-chain fatty acids in complex biological matrices via GC-MS or LC-MS.
• Metabolic Pathway Tracing: Enables detailed investigation of lipid metabolism, absorption, and distribution in pharmacological and nutritional studies.
• Pharmaceutical Research: Employed in the development and validation of analytical methods for drug formulations and pharmacokinetic studies involving lipid-based drug delivery systems.
• Biochemical Research: Acts as a tracer to study enzyme kinetics, lipid biosynthesis, and membrane dynamics in vitro and in vivo.
• Material Science: Can be used in the synthesis of labeled surfactants, lubricants, or polymers to study their structure, properties, and degradation mechanisms.
