Description

(E/Z)-2-Cyano-3-Methyl-2-Pentenoic Acid Ethyl Ester-D3 is a high-purity, deuterium-labeled chemical intermediate of significant importance in advanced research and development. This compound matters for its role as a stable isotope-labeled building block, enabling precise analytical studies in pharmacokinetics, metabolism, and environmental fate. It is primarily needed by pharmaceutical R&D laboratories, agrochemical innovators, and analytical service providers engaged in tracer studies and mass spectrometry-based quantification.

Application

• As a deuterated internal standard for the accurate quantification of its non-labeled counterpart or related metabolites via LC-MS/MS and GC-MS.
• A key labeled synthetic intermediate in the research and development of novel active pharmaceutical ingredients (APIs), particularly for metabolism and degradation pathway studies.
• Used in agrochemical research for tracing the environmental fate and metabolic pathways of pesticides and herbicides.
• Employed in mechanistic organic chemistry studies to investigate reaction pathways and kinetic isotope effects (KIE).
• Serves as a specialized building block for the synthesis of deuterium-labeled fine chemicals and complex molecules for research purposes.

Quality Control

Our deuterated compounds are produced under strict quality control protocols to ensure high chemical and isotopic purity, which is critical for analytical applications. Each batch is characterized by NMR, HPLC, and mass spectrometry to confirm structure, chemical purity, and deuterium incorporation levels. Certificates of Analysis (COA) detailing these parameters are available upon request, providing full traceability and assurance for your research.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This material is moisture-sensitive; keep the container tightly sealed in a dry environment.
