Description

Rac 1,2-Bis-Palmitol-3-Chloropropanediol-D5 is a deuterated isotopologue of a chloropropanediol fatty acid ester, serving as a critical analytical standard and synthetic intermediate. Its primary value lies in enabling precise quantification and metabolic pathway tracing in lipid research and food safety analysis. This compound is essential for researchers and quality control laboratories in the pharmaceutical, food science, and analytical chemistry sectors who require high-purity, structurally defined reference materials.

Application

• Internal Standard for Mass Spectrometry: Used as a deuterium-labeled internal standard for the accurate quantification of chloropropanediol (MCPD) esters and related contaminants in edible oils and food products via GC-MS or LC-MS.
• Metabolic Tracer Studies: Employed in lipid metabolism and toxicology research to trace the biochemical fate and transformation of chloropropanediol esters in biological systems.
• Method Development & Validation: Critical for developing, calibrating, and validating analytical methods in compliance with food safety regulations (e.g., EFSA, FDA) for process contaminants.
• Reference Material Production: Serves as a certified reference material (CRM) or high-purity building block for synthesizing other labeled analogs for complex matrix analysis.
• Pharmaceutical Impurity Profiling: Acts as a standard for identifying and quantifying potential genotoxic impurities in pharmaceutical formulations containing fatty acid derivatives.
