Description

3-Chloro-1,2-Propanediol-1,1,2,3,3-D5 1-Palmitate Standard is a high-purity, isotopically labeled chemical standard essential for advanced analytical applications. This deuterated compound serves as a critical reference material for precise quantification and method validation in complex matrices. It is primarily required by analytical laboratories, research institutions, and quality control departments in the pharmaceutical, food safety, and environmental monitoring sectors where accurate detection of chloropropanediol esters is paramount.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a stable isotope-labeled internal standard in GC-MS and LC-MS/MS analyses for the accurate quantification of 3-MCPD esters and related process contaminants.
• Method Development and Validation: Essential for developing, calibrating, and validating analytical methods in compliance with regulatory guidelines from agencies like the FDA and EFSA.
• Food Safety Analysis: Critical for testing edible oils, infant formula, and processed foods for chloropropanediol fatty acid esters (MCPDEs) and glycidyl esters (GEs).
• Metabolic and Toxicological Studies: Employed in research to trace the absorption, distribution, metabolism, and excretion (ADME) of chloropropanediol compounds in biological systems.
• Quality Assurance/Quality Control (QA/QC): Used to ensure the accuracy and precision of routine testing protocols in commercial and contract testing laboratories.
• Certified Reference Material (CRM) Production: Serves as a primary material for manufacturers producing certified reference materials for proficiency testing and laboratory accreditation.

Quality Control

This analytical standard is produced under strict quality control protocols to ensure the highest isotopic and chemical purity for trace analysis. Each batch is characterized using advanced techniques including NMR and high-resolution mass spectrometry. A comprehensive Certificate of Analysis (COA) is provided, detailing the isotopic enrichment, chemical purity, and concentration. Our quality system is designed to support GLP/GMP-compliant laboratory workflows and regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. Allow the vial to equilibrate to room temperature before opening to prevent moisture condensation. Store in a cool, dry, and well-ventilated area.
