Description

Thiophene-2,5-D2 CAS NO 2041-42-1 is a deuterated derivative of thiophene, specifically labeled at the 2 and 5 positions, serving as a critical stable isotope-labeled compound. This product is essential for advanced research and development, providing a non-radioactive tracer for mechanistic studies, metabolic pathway analysis, and as an internal standard in quantitative analytical methods like mass spectrometry. It is primarily needed by pharmaceutical R&D laboratories, agrochemical innovators, and academic institutions engaged in spectroscopy and reaction kinetics studies where precise molecular tracking is required.

Application

• As a stable isotope-labeled internal standard for the accurate quantification of thiophene or related compounds in complex matrices using GC-MS or LC-MS.
• For deuterium labeling studies in pharmaceutical research to investigate drug metabolism, pharmacokinetics (DMPK), and metabolic stability.
• Use in NMR spectroscopy as a tool for mechanistic organic chemistry and structural elucidation, where deuterium substitution simplifies spectra.
• In material science research for studying the synthesis and properties of deuterated polymers or organic electronic materials.
• As a specialized building block in organic synthesis for preparing deuterated analogs of more complex molecules in agrochemical and pharmaceutical discovery.
• For academic and industrial R&D focused on reaction mechanisms, isotope effects, and catalytic processes.

Quality Control

Our Thiophene-2,5-D2 is produced and handled under strict quality protocols to ensure high isotopic purity and chemical integrity, critical for sensitive analytical applications. Each batch is characterized by advanced spectroscopic methods, including NMR and mass spectrometry, to confirm deuteration level and chemical purity. Certificates of Analysis (COA) detailing isotopic enrichment (e.g., D atom %), chemical purity, and solvent residues are provided and available upon request, supporting compliance with rigorous research standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at controlled room temperature (15-25°C). For long-term stability, consider storage under an inert atmosphere such as argon or nitrogen to prevent potential oxidation or moisture uptake.
