Description

Rac-1-Palmitoyl-2-Linoleoyl-3-Chloropropanediol-D5 is a deuterated isotopologue of a chloropropanediol fatty acid ester, serving as a critical analytical standard and reference material. Its primary value lies in enabling precise quantification and metabolic pathway tracing in complex biological and food matrices. This compound is essential for researchers and quality control laboratories in the food safety, lipidomics, and toxicology sectors who require high-purity, isotopically labeled internal standards for mass spectrometry.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterium-labeled internal standard for the accurate quantification of 3-monochloropropane-1,2-diol (3-MCPD) esters and related process contaminants in foods like refined vegetable oils and infant formula.
• Food Safety & Contaminant Analysis: Critical for method development and validation in regulatory testing for chloropropanols, ensuring compliance with international food safety standards (e.g., EFSA, FDA).
• Lipid Metabolism Research: Employed in tracer studies to investigate the digestion, absorption, and metabolic fate of structured lipids and processed fat derivatives.
• Toxicological Studies: Facilitates precise pharmacokinetic and metabolic profiling of chloropropanediol esters in in vitro and in vivo models.
• Quality Control & Method Certification: Used by testing laboratories and proficiency scheme providers to certify analytical methods and ensure inter-laboratory comparability.
• Reference Material Production: Serves as a primary calibrant for manufacturing certified reference materials (CRMs) for the food and feed industry.

Quality Control

Our Rac-1-Palmitoyl-2-Linoleoyl-3-Chloropropanediol-D5 is manufactured under strict quality protocols to ensure the high chemical and isotopic purity required for analytical applications. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, HPLC, and GC-MS, to confirm identity, isotopic enrichment (D5), and chemical purity. A comprehensive Certificate of Analysis (COA) detailing batch-specific data is provided to support your research and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
