Description

Ethyl Acetate-D3 CAS NO 90691-33-1 is a deuterated isotopologue of the common solvent ethyl acetate, where three hydrogen atoms are replaced by deuterium. This stable isotope-labeled compound is essential for advanced analytical and research applications where precise molecular tracking is required. It is a critical material for scientists and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors.

Application

• Internal Standard for Quantitative Analysis: Used as a stable, non-interfering reference in GC-MS, LC-MS, and NMR for accurate quantification of ethyl acetate or related compounds in complex matrices.
• Metabolic Pathway Tracing: Serves as a deuterium-labeled tracer in pharmacokinetic and metabolic studies to investigate drug absorption, distribution, metabolism, and excretion (ADME).
• Solvent for Specialty Synthesis: Employed as a deuterated solvent in reactions where proton exchange must be minimized or in NMR spectroscopy to avoid signal interference from the solvent.
• Pharmaceutical Impurity Profiling: Acts as a reference standard in the identification and quantification of process-related impurities and degradation products in active pharmaceutical ingredients (APIs).
• Polymer and Material Science Research: Utilized in mechanistic studies of polymerization reactions and for analyzing the composition of polymers and coatings.
• Forensic and Environmental Analysis: Applied as a labeled standard in the detection and measurement of volatile organic compounds (VOCs) in environmental samples or forensic investigations.

Quality Control

Our Ethyl Acetate-D3 is produced under strict quality management systems to ensure the highest isotopic and chemical purity for research and analytical applications. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, GC-MS, and HPLC, to confirm isotopic enrichment, chemical identity, and purity. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (e.g., D atom %), chemical assay, and solvent residue profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to its volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and potential contamination.
