2-Chloro-1,3-propanediol-d₅(CAT: R012984) is a deuterium-labeled analog of 2-chloro-1,3-propanediol (commonly known as 3-MCPD), a chemical of concern due to its presence as a food processing contaminant. The incorporation of five deuterium atoms makes this compound ideal as an internal standard for mass spectrometry-based analysis, allowing accurate quantification and differentiation in complex matrices. It is widely used in food safety, toxicology, and environmental studies to monitor exposure and understand metabolic pathways. 2-Chloro-1,3-propanediol-d₅ is valuable for validating analytical methods and supporting regulatory compliance in contaminant detection. Suitable for GC-MS and LC-MS applications.
