Description

2-Chloro-1,3-Propanediol-D5 Distearate is a deuterated derivative of a chloropropanediol distearate ester, serving as a critical stable isotope-labeled internal standard for advanced analytical chemistry. This compound is essential for ensuring the accuracy and reliability of quantitative analyses, particularly in complex matrices. It is primarily used by researchers and quality control laboratories in the pharmaceutical, food safety, and environmental monitoring sectors who require precise measurement of related compounds.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterium-labeled reference compound for the accurate quantification of 2-chloro-1,3-propanediol (2-MCPD) esters and related process contaminants via GC-MS or LC-MS/MS.
• Food Safety Research: Critical for method development and validation in the analysis of fatty acid esters of chloropropanols (e.g., 3-MCPD, 2-MCPD) in refined edible oils, infant formula, and other processed foods.
• Pharmaceutical Impurity Profiling: Employed in stability studies and impurity tracking for drug substances and products where related compounds may form during synthesis or storage.
• Metabolic and Toxicological Studies: Facilitates the study of the absorption, distribution, metabolism, and excretion (ADME) of chloropropanediol esters in biological systems.
• Method Development & Validation: Serves as a key component in establishing robust, compliant analytical methods for regulatory submission and quality control protocols.
• Environmental Analysis: Potential use in tracing and quantifying similar organochlorine compounds in environmental samples.
