Description

Ethyl-D5 Carbamate is a deuterated isotopologue of ethyl carbamate, where five hydrogen atoms are replaced with deuterium. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring high analytical accuracy and reproducibility. It is a critical reagent for researchers and quality control laboratories in the pharmaceutical, food safety, and environmental monitoring sectors, particularly for the precise analysis of ethyl carbamate (urethane) levels.

Application

• Internal Standard for Mass Spectrometry (MS): Primary use as a quantitative internal standard in GC-MS or LC-MS/MS methods for the accurate determination of ethyl carbamate.
• Pharmaceutical Research & Metabolism Studies: Used in pharmacokinetic, metabolic pathway tracing, and drug degradation studies due to its isotopic stability.
• Food & Beverage Safety Analysis: Critical for monitoring and quantifying ethyl carbamate, a process contaminant, in fermented foods and alcoholic beverages like wine, spirits, and soy sauce.
• Environmental and Toxicological Testing: Employed in analytical methods to detect trace levels of urethane in environmental samples or biological matrices.
• Certified Reference Material (CRM) Production: Serves as a key component in the formulation of certified reference materials for laboratory proficiency testing and method validation.
• Organic Synthesis Intermediate: Can be utilized in synthetic chemistry for the preparation of other deuterated compounds where the carbamate or ethyl-D5 moiety is required.
